2 LIVE LINE WORK
2.1 RECOGNITION OF LIVE LINE WORK
Live line work is work performed on or near components of a transmission network circuit that is
capable of being energised to high voltage without implementing the full protective practice of
isolating, proving de-energised and earthing at the work site. A task shall also be live line workwhen Transend declares that it is live line work or when any part of a helicopter and attachments,
including any supported person or load, is within 5 metres of a transmission network circuit
capable of being energised without implementing the full protective practice of isolating, proving
de-energised and earthing at the work site.
2.2 COMPLIANCE WITH CODES, PROCEDURES AND GUIDELINES
All work is to comply with:
the Power System Safety Rules;
ENA / ESAA Guidelines; and
this standard.
2.3 WORK PROCEDURES
The Service Provider is to develop and issue work procedures for all live line tasks in accordance
with ENA / ESAA guidelines. Live line work is only to be carried out in accordance with these
work procedures. On-site modifications to work procedures that have the potential to reduce the
level of safety are prohibited.
The Service Provider is to ensure that Transend has been provided with a current copy of the work
procedures to be used and Transend is informed in writing of the site specific details. The aim of
the procedure is to identify and communicate risk and show how the risks are to be managed by the
Service Provider.
Live line work shall not commence until Transend advises the Service Provider that it has reviewed
the procedures. The Service Provider is to allow sufficient time for this review to occur. To assist
Service Providers, a guide to work procedures is included in this standard.
The Service Provider is to ensure that work procedures are proven in a trial on de-energised
components to verify the work can be carried out reliably and safely with the resources listed.
An authorised and approved copy of the live line procedure being carried out is to be available at
the work site.
2.4 LIVE LINE WORK METHODS
All live line work shall be performed under a Live Line Permit to Work. The Live Line Permit to
Work shall be issued in accordance with Appendix A of this standard.
2.4.1Live Line Stick Method
(a) Minimum Safe Approach Distances for Live Line Stick Work
The live line stick method is based on the principle that the lineworker always maintains a
minimum approach distance from any energised high voltage line and apparatus while
performing work using tools and equipment fitted to insulating live line sticks. The
minimum approach distances are stated in Table 1 and are based on a maximum transient
over-voltage of three times rated voltage with an inadvertent movement distance of 300mm.

All clothing, including body belt straps, shall be secured to prevent the minimum approach
distance from being compromised.
Tool insulation distances (the total length of insulating material less metal end fittings and
hand hold areas) shall not be less than the minimum approach distance.
(b) Live Line Stick Work and Disc Insulators
During live line stick work the minimum number of electrically sound and functioning disc
insulators, in addition to any bonded (shunted) discs, should be as stated in Table 2.

Live line stick work may be performed with fewer sound insulators than shown provided the
Service Provider has specific work practices for that situation. These may include properly
coordinated temporary air gaps or surge arresters fitted in the vicinity of the work site.
(c) Elevated Working Platforms for Live Line Stick Work
Elevated working platforms (EWP) and associated materials handling devices are to comply
with ENA guidelines. The elevated working platform is to be earthed in accordance with the
Service Providers procedures. Where hydraulic couplings are provided on the platform for
tools, the tools shall be of a type approved for live line work and shall use a combination ofinsulating hoses and oil approved and tested for live line use.
(d) Conductive Clothing for Live Line Stick Work
Conducting footwear including socks shall be provided by the Service Provider, and should
be worn, when it is considered that the uncontrolled discharge of electrostatic charges could
affect lineworkers comfort and safety. Conductive clothing shall be worn where necessary
to limit discomfort from induced static discharges.
(e) Live Line Sticks
Hollow sticks are not acceptable due to difficulties in maintaining their electrical integrity.
The live line minimum approach distance should be indicated on the insulating stick for the
voltage being worked. Timber live line sticks shall not be used.

2.4.2Glove and Barrier Method
(a) General Glove and Barrier Techniques
The live line glove and barrier method is based on the principle that the lineworker always
maintains a minimum of two levels of insulation to prevent phase to earth or phase to phase
contact. This is achieved by wearing appropriately rated and tested insulating gloves andsleeves, and always working from an approved elevated working platform or insulating
platform and never directly from a ladder, pole or structure. Additional protection for the
lineworker is provided by using insulating barriers and fitting on insulating basket liner in
the EWP. This technique is never to be used on voltages above 33 kV AC rms phase to
phase. Procedures must be developed to ensure that work is conducted on one phase at a
time.
Service Providers must ensure that all Glove and Barrier procedures emphasise that all
components in the immediate work area that could be at a different potential from those
being worked on by the live line worker, shall be covered with insulating barriers. This
includes energised conductors, earthed conductors or stay wires that are within reach of the
live line worker.(b) Combination of Glove and Barrier with Stick Methods
Work procedures using a combination of Glove and Barrier and Stick methods shall ensure
that safety margins are not compromised by live line sticks entering within one metre of the
live line worker. Service Providers are to ensure that Glove and Barrier methods are not used
from an insulated elevated platform while a line worker is carrying out stick methods from
the same platform or from a pole or structure.
(c) Protective Clothing for Glove and Barrier Methods
All live line workers shall wear insulating eye protection, Gloves and Sleeves at all times
while within one metre of energised lines or components. Any live line worker changing
from the stick method shall ensure that insulating Gloves and Sleeves are worn before
coming within one metre of energised components or lines.
Insulating Glove, Sleeves and Flexible Barriers designed for High Voltage live line work are
available in four classes as per Table 3.
Table 3 - Maximum Use Voltage
Class
Maximum Use
Voltage kV
(Phase to Phase)
1 7.5
2 17.03 26.5
4 36.0
The Service Provider shall ensure that insulating gloves and sleeves are cleaned and dried in
accordance with manufacturers instructions. Gloves are not to be worn inside out.
Insulating gloves and sleeves are to be stored protected from mechanical or chemical damage
and in their respective storage bags without creasing and not stored inside out.

UNCONTROLLED WHEN PRINTED
Before use, insulating gloves and sleeves shall be:
field air-tested;
visually inspected both inside and out for pin holes, cuts, scratches, ageing,
abrasions, corona cutting or mechanical damage; of the correct class for the circuit voltage;
clean and dry; and
dusted internally with pure talcum powder.
Cotton clothing is to be worn under insulating sleeves and cotton gloves covering the wrist
beneath the insulating gloves. Clean leather protective gloves are to be worn over insulating
gloves at all times. Protective gloves that have been heavily contaminated by any oil based
substances, to the extent that insulating gloves and sleeves may be damaged, shall be
discarded.
(d) Insulated Elevating Work Platforms for Glove and Barrier Methods
Elevating work platforms and associated materials handling devices are to be designed for
live line glove and barrier method and comply with the ENA guidelines. It shall be fitted
with:
an insulated section in the upper boom rated to 60 kV;
an approved insulating liner rated to 50 kV fitted into the basket;
a safety belt attachment point; and
a non slip surface.
Where hydraulic couplings or tools are provided on the platform or upper boom, all the
hoses connected to tools and the lower boom shall be non-conductive, tested and approvedfor live line use. Only approved hydraulic tools with insulated hoses and oil shall be
permitted.
The Service Providers procedures are to ensure that any elevated working platform is
inspected immediately prior to use for the following:
high voltage test certificate is current;
all insulating components are to be visually inspected and wiped clean with asilicone impregnated cloth;
the insulating boom and basket are free of debris; and
the chassis of the elevated working platform is to be effectively earthed inaccordance with the Service Providers procedures before Glove and Barrier
procedures are carried out.
The Service Provider is to take such measures as to ensure that during use the insulated
boom or basket shall not contact uninsulated conductors or earthed objects. All persons at
ground level or potential are to be kept clear while live line Glove and Barrier work is being
performed.
The Service Provider shall ensure that if any work is carried out on the insulated elevated
working platform that could affect its insulating qualities then the elevated working platform
is to be tagged as not to be used for Glove and Barrier methods until it is successfully
electrically tested.

Where an elevated work platform or insulating platform is to be used between circuits then
adequate insulating barriers rated for the higher voltage are to be fitted to the lower circuit
and a minimum clearance of 300mm maintained between the platform and the lower circuit.
2.4.3Bare Hand Method
(a) Bare Hand Working Methods
Live line bare hand methods allow live line workers wearing conductive clothing to perform
work in contact with energised components while insulated from earth or other electrical
potential.
The minimum safe approach distances as per Table 4, shall be strictly observed at all times.
Table 4 - Minimum Safe Approach Distances for AC Systems
Nominal Line
Voltage (kV)

11 330 350
22 380 425
110 940 1290
220 1580 2260
These air gaps are calculated using a maximum transient over voltage factor of three and an
inadvertent movement distance of 600mm up to 66 kV and 300mm for higher voltages. A
greater inadvertent movement tolerance may be applicable depending upon the ergonomic
considerations, environment and the procedure.
Bonding tails and other items are to be secured to prevent any chance of unravelling and
subsequent infringement of the minimum safe approach distance.
The bare hand live line worker shall effectively bond their suit to energised metal.
Conductive gloves may be used for initially bonding to a conductor so long as the worker is
not connected to any other worker or large item of equipment. The initial charging current
may be significant so where the worker is connected to others or to equipment then initial
contact should be made by means of a conductive wand or clamp.
Work Procedures are to be designed to ensure that the bare hand line worker does not allow
their conductive clothing to bridge line components at different potential. Bonds are to be
placed where this may occur such as when separating two components in an insulatorassembly.
Where live line rope hoists are used to transfer live line workers to energised conductors, an
independent safety rope of equivalent electrical properties to the live line rope shall be used
to secure them to the line. Whenever practical, a length of live line stick shall be used in
series with the live line rope to increase the electrical security.
(b) Protective Clothing for the Bare Hand Method
Conductive overalls including head covering, conductive gloves, conductive socks and
conductive boots shall be worn at all times by line workers energised at line potential. All
items of clothing are to be securely bonded together and the hood is to be worn over the peak
of the safety helmet to ensure the face is shielded. Other work clothing is to worn under thesuit. Protective gloves may be worn over the conductive suit but if they are nonconductive

then they must not be fitted until after the worker has completed bonding.
Procedures shall remind Bare Hand live line workers that metal jewellery, belt buckles and
watches, mobile phones etc. are not to be worn since heat may be generated by induced
circulating currents.
(c) Bare Hand Method and Insulator Strings
Conductive suits should not be allowed to degrade the performance of insulator strings.
Where contact between the suit and discs in the string is likely then a bond shall bypass the
discs involved.
Strings containing porcelain disc insulators shall have each disc electrically tested prior to
performing live line bare hand maintenance work within the minimum safe approach
distance of the string. This testing should preferably be performed immediately prior to
starting work. This requirement does not apply to glass disc, synthetic and long rod
insulators.
Approved instruments and techniques shall be used to ensure defective insulators are
detected. Instruments used to test insulators should be capable of reliably detecting defectiveinsulators and buzz sticks are not to be used. The voltage across each disc in the string is to
be recorded if a line voltmeter is used.
At all times during live line bare hand work performed within the safe approach distance of a
glass or porcelain disc insulator string, the minimum number of electrically sound and
functioning disc insulators, in addition to any bonded (shunted) discs, shall be:
Table 5 - Minimum Number of Sound Disc Insulators
Nominal Line VoltageAC

Sound Disc Insulators
Up to 66 3
110 4
220 7
Live line Bare Hand work may be performed with fewer sound insulators than shown
provided properly coordinated temporary air gaps or surge arresters are fitted in the vicinity
of the site work.
Any insulator or insulator string exhibiting significant signs of distress such as louder than
normal noise levels or visible signs of intermittent surface discharging shall not be changed
using live line Bare Hand techniques irrespective of the number of sound disc insulators in
the string or circuit voltage.
2.4.4Use of Helicopters
(a) General Requirements for Live line Helicopter Work
The Service Provider shall supply helicopters in accordance with ESAA guidelines. Single
engine helicopters should not be used where the emergency recovery procedure requires the
aircraft to climb or where workers are suspended.
Prior to the work commencing, the Service Provider shall identify any hazards that have a
potential to impact on the safe outcome of the work. This is to include the condition of anyline or structure for damage, corrosion, defective insulators, over-crossings, vegetation etc.

Phase (m)
up to 66 1.4 1.6
110 1.7 2.0
220 2.5 3.2
These air gaps are based on a transient over-voltage factor of 3, for altitudes up to 900m and
a 0.9 metre tolerance for differential conductor movement, construction tolerances and the
degrading effect on the electrical strength of the air gap due to the helicopter acting as a
charging and discharging electrode during bonding and un-bonding. Additional allowanceshall be made by the Service Provider to ensure that helicopter parts or rotors, the maximum
reach of the worker, inadvertent sagging or dropping of tools or bonding wands will not
enter the minimum clearance distance. Altitude correction factors shall apply to work above
900m.
All tools and equipment used shall be designed and tested for helicopter live line work.
Live line work shall cease when the helicopter pilot considers the general weather, visibility,
wind or turbulence may impact on the safety of flying operations.
Effective communications shall be provided between the helicopter crew, live line workers,
ground support crew and Safety Observer if one has been appointed. If the pilot cannot
maintain effective continuous observation of any live line workers during helicopter slingoperations then the Service Provider shall provide suitably trained helicopter crew to carry
out this role.
The Service Provider is to effectively manage any public safety issues including traffic
control and keeping members of the public clear of the work site and the landing zone.
(b) Protective Clothing for Live Line Helicopter Work
Conductive clothing including overalls with head covering, conductive gloves, conductive
socks and conductive boots shall be worn at all times by line workers and all helicopter crew.
All items of clothing are to be securely bonded together and to the helicopter. Other work
clothing is to be worn under the suit. Protective gloves may be worn over the conductive suit
but if they are nonconductive then they must not be fitted until after the worker has
completed bonding.
(c) Bonding for Live Line Helicopter Operations
All tools and the live line worker shall be bonded together using robustly constructed leads
with a resistance of less than one ohm. Breakaway attachments shall be provided for all tools
and equipment to simultaneously connect the helicopter, the live line worker and the line.
The main bonding lead shall be designed to be pulled free without damaging the line or the
helicopter.
Where the live line worker is bonded to a large conductive object such as a platform or
helicopter, initial bonding on to the conductor shall be made by means of a conductive wand
or clamp.

2.8 WORKING PRACTICES AND CONDITIONS
2.8.1Work Briefings
The Service Provider is to ensure that all live line workers, including Safety Observers, helicoptersupport crew and pilot, are briefed before live line work commences. Briefings are to include:
why the work is to be done;
what is to be accomplished;
how the work is to be carried out in line with Live Line Work Procedures; and
who will do what.
Information should include site and circuit information, how the work is to progress using the Live
Line Work Procedures and techniques described, any hazards at each stage, the contingency
measures in place and the required actions in case of an incident.
2.8.2Minimum Safe Approach Distances
Maintaining minimum electrical clearances, as given in this standard, is only a subset of the
integrated safety management system. Service Providers are expected to effectively manage the
overall risk of on-site live line operations and conduct a risk assessment that may increase these
minimum electrical clearances. Consideration must be given to:
allowance for conductor movement;
the duration of incursion;
the number of live line workers involved;
increased likelihood or dimension of switching surges;
the likelihood of inadvertent movement; and
the use of cranes, excavators or other large planes of metal.
Minimum safe approach distances less than those given in Tables 4 and 6 may be used for bare
hand or helicopter work only if the maximum transient over-voltage expected are known to be
lower than the value assumed in ENA / ESAA guidelines or provided properly coordinated
temporary air gaps or surge arresters are fitted in the vicinity of the work site, ref ANSI / IEEE
standard 516. Transend are to be informed of all assumptions, calculations and equipment prior to
any work commencing.

an electrical storm is expected or observed in the vicinity of the work site or the circuit;
rain, mist, fog, smoke, snow or sleet is present unless using tools or techniques specificallyapproved for the site conditions;
any threat of rain, mist, fog, snow or sleet while using insulating rope;
windy or blustery conditions likely to threaten safe working or produce excessivemovement of tools, conductors, cranes, helicopter or platforms; or
sufficient light is not available.
2.8.4Fault Protection
The circuit is to be fitted with devices to detect fault conditions and open the circuit. These devices
are to be in an operational state during live line working. In the event of a circuit trip, a reclose is
not to be attempted until:
the safety of the work team or teams has been established;
all work team or teams have confirmed that they are clear of the circuit; and
authorisation to reclose the circuit is obtained from Transend.
2.8.5Auto-Reclose Facility
The Service Provider is to document and implement Work Procedures to ensure that each auto-
reclose facility on the circuit is identified, disabled and tagged out of service before issue of the
Permit to Work allowing live line work to commence. Approval from Transend is to be obtained to
disable auto-reclose facilities.The Work Procedure is to ensure that each auto reclose facility shall
be returned to service once all work teams working on the circuit have completed work and
approval has been obtained from Transend.
2.8.6Work Team Communications
Service providers shall ensure each live line work team establishes and maintains an effective andcontinuous on-site two-way communication link with the system controller. The effectiveness of
the link is to be checked at regular intervals during the course of the work. Service providers shall
also provide an additional communication system between pilot, line worker, safety observer and
ground based work team members for helicopter operations.
2.8.7Public Safety
The Service Provider is to ensure that members of the public or personnel not related to the live
line operation are to keep clear of the work site.
2.8.8Work on De-energised Components
Live line practices, including helicopter practices, may be used on de-energised componentsprovided all work is undertaken and all procedures fully observed as though the circuit is energised.
Service providers utilising Transend assets for live line training purposes shall gain approval from
Transend. The description of work will include the training of linesmen in live line methods and
the requirements of isolation and earthing where appropriate.
2.8.9Use of Cranes
The crane operator is to be under the direct supervision of one nominated member of the live line
team. Prior to work, crane operators are to be:
introduced to the site;
instructed on safe working distances on the site and why they are to be enforced;

familiar with the communication technique to be used and how to raise concerns with thelive line team;
aware of which team member are to be issuing commands and the authority of the SafetyObserver to stop the work; and
qualified as an Instructed Person and sign on the Live Line Permit to Work.
2.8.10 Suspension of work
If it becomes necessary to suspend work then the Service Provider must leave the circuit in a safe
condition and Transend is to be informed. Transend is to be consulted before work re-commences.
2.8.11 Identification of Hazards
The Service Provider is to produce procedures that ensure prior to work starting:
the circuit has been correctly identified;
all hazards have been identified; and
any line to be worked on conforms with the expected type of construction and has the clearances
expected for which the Work Procedures was planned and assessed.
2.8.12 Insulating Barriers
Insulating barriers are designed to protect workers in case of accidental contact, not to enable
minimum safe approach distances to be reduced. Insulating barriers shall be fitted in the immediate
work area to prevent inadvertent phase to phase or phase to earth contact as required by the Service
Providers work procedures. They should not be used to provide insulation between components
and shall not be deliberately touched without the use of a live line stick or a rated insulated glove.
Insulating barriers should normally be applied from below the conductors and the order of fittingshould cover the nearest or lowest energised component first. The order in which they are removed
would normally be the reverse order in which they are fitted. However, each site may have unique
requirements and barriers should be used with care to reduce the total risk to line workers.
2.8.13 Use of Ladders
All ladders are to be approved for live line work and secured by rigging or live line sticks to
prevent inadvertent movement.
2.8.14 Other work on the Site or Circuit
Live line work shall not be carried out while any other work on the site or circuit has the potential
to compromise the safety of the work team.
2.8.15 Integrity of Mechanical Properties
Prior to live line work starting, the Service Provider is to ensure that any structure or conductor to
be used or climbed and all adjacent structures are mechanically suitable and in a condition to
support the load. Physical clearances between phases and between phase and earth, including mid
span clearances, are to be checked as appropriate, by the Service Provider.
2.8.16 Integrity of Electrical Properties
Prior to live line work starting, the Service Provider is to ensure that any non-conducting structures
where suspected component damage or excessive moisture and pollution conditions exists such that
leakage currents may be excessive, an electrical leakage current test shall be carried out using
approved instruments. Where reduced insulating properties are suspected and access to the work is
via a wooden pole then an earth leakage test should be carried out before climbing.

UNCONTROLLED WHEN PRINTED
Any insulator or insulator string exhibiting significant signs of distress such as louder than normal
noise levels or visible signs of intermittent surface discharging shall be approached with care using
techniques designed to reduce the risk of flashover and subsequent injury. If the circuit potential is
at 33 kV or above, the insulator shall not be changed or tested using live line techniques
irrespective of the number of sound disc insulators in the string.
Where live line work is to be carried out close to porcelain disc insulators, each disc is to beelectrically tested immediately prior to work since a puncture failure may not be visible to the line
worker. Approved instruments and techniques shall be used to ensure defective insulators are
detected. The voltage across each disc in the string is to be recorded if a line voltage meter is used.
2.8.17 Insulator Washing
Prior to live line insulator washing work, the Service Provider is to develop a specific live line
Work Procedure for Insulator Washing in accordance with ENA / ESAA guidelines and
ANSI/IEEE 957, Guide for Cleaning of Insulators. The procedures are to ensure that auto-reclose
facilities are disabled and tagged out of service for the duration of the work.
2.9 PROCEDURES IN THE EVENT OF AN INCIDENT
An incident is:
an electric shock or other injury to any person;
a flashover at or close to the work site for any reason;
complete or partial breakdown of any tool or equipment regardless of if a flashover hasoccurred;
the electrical or mechanical failure of any tool which had the potential to cause an accident;
the failure or malfunction of any component of a helicopter which did, or could have thepotential to cause an accident; or
any action or near-miss event which could have the potential to cause an accident.
The Service Provider is to ensure that documented procedures are in place to respond to the above
incidents covering:
rescue;
first aid and safety of other persons at the site;
emergency switching requirements;
restoration of circuits;
investigation and reporting requirements; and
notification to all required parties.
2.10 GUIDELINES FOR WORK PROCEDURES

(d) Name and title of the person who has approved the document on behalf of the ServiceProvider;
(e) List of the minimum resources required including:
tools, clearly stating the maximum loading conditions if applicable; equipment including ladders, safety barriers, notices;
parts or spares or disposable items; and
line workers qualifications, numbers and personal protective equipment.
(f) Checklist of actions to be completed prior to live line work starting to ensure hazards areidentified, the risk due to each hazard is assessed, control measures determined and
implemented. Site specific hazards may include the condition of towers or disc insulators,
traffic or live stick management, mid-span clearances, weather forecast, terrain stability,
public safety etc;
(g) Transends requirements for accessing the network;
(h) Guidelines on the content of Work Site briefings;
(i) Minimum electrical clearance to be observed and how this is to be achieved;
(j) Breakdown of work and how it is to progress indicating any milestones. The logical flow ofthe work should be transparent while designed to minimise the overall risk by reducing the
duration of exposure and the number of changes between different types of live line work
methods or movements from one phase to another. Live line work would normally be
conducted on one phase at a time;
(k) Identification of the risks associated with carrying out this specific procedure and how eachrisk is being managed, eg. communications, Safety Observer, barriers, inspections etc;
(l) Analysis of the residual likelihood (including frequency or duration) and the consequencesof each identified risk;
(m) Identification of recovery or contingency measures that are to be in place;
(n) Consideration of how performance is to be monitored and reviewed.
Four types of live line methods have been identified and guidelines have been produced by ENA /
ESAA. They are Line Stick, Glove and Barrier, Bare Hand and Helicopters for Live Line Work.
Service Providers may develop procedures that use more than one method if the guidelines for each
are observed. However, extreme caution is required since the work methods are distinctly different
and unsafe work practices could result if care is not exercised.
3 COMPLIANCE AND PERFORMANCE AUDIT
Transend will comply with the ENA / ESAA guidelines on live line working. Transend will inspect
the performance of live line field work for compliance with this standard at least once in any 12
month period. Transend will monitor and review this Live Line Working Standard in line with
performance audit results and best practice.
Transend shall conduct sufficient audits of the Service Providers records to ensure administrative
compliance with this standard in areas such as live line workers competence and the purchasing
and testing of live line tools and equipment.
The Service Provider shall monitor the performance and assess the competence of the live line
worker by conducting field inspections at least once in any 12 month period. The field inspections
are to be conducted by a person experienced in live line techniques and who is independent of the
work party.
