A. Visual and Mechanical Inspection
1. Document equipment nameplate data on test report. Verify that
equipment nameplate ratings are in accordance with the final approved
or record drawings and specifications, if available.
2. Visually inspect the components for damage and errors in polarity or
conductor routing.
(a) Verify that the ground connection is made ahead of the neutral
disconnect link, and on the line side of any ground fault sensor.
NOTE: In some cases, Generator neutrals are also bonded to ground
in a similar fashion as service entrance bonds are used for
commercial power connections. In these cases, neutral sensors are
used in the bond connection and differentially connected within the
Ground Fault detection system.
(b) Verify that proper polarity exists for both primary and secondary
connectors to the neutral sensors.
(c) Verify that all phase conductors and the neutral pass through the
sensor in the same direction for zero sequence systems.
(d) Verify that grounding conductors do not pass through zero sequence
sensors.(e) Verify that the grounded conductor (usually Neutral) is bonded to ground
in accordance with the power system specifications. Bonding to ground
is permitted at the service entrance only with the exception of double
ended systems with a single center bond and/ or on the secondary of a
separately derived power systems including generators. Power systems
may have multiple service entrances and multiple bonding at the
multiple service entrances. Bonding to ground is not permitted
downstream of the service and separately derived equipment.
NOTE: Refer to the special operating and testing instructions
supplied with the equipment, if available.
3. Verify tightness of all electrical connections, including control circuits.
4. Verify correct operation of all functions of the self-test panel.
5. Verify that the control power transformer has adequate capacity for the system.
6. Set pickup and time-delay settings in accordance with the settings
provided in the owner's specifications.
B. Electrical Tests
Verify the proper selection and operation of the electrical test equipment.
Record the date of the last calibration date and the date re-calibration is due.
1. Measure the system neutral-to-ground insulation resistance with the
neutral disconnect link temporarily removed. Replace the neutral
disconnect link after testing.
2. For a system: that involves only one source; is a ground fault protection
system that uses a zero phase sequence sensor that encompasses allphase and neutral conductors; and has a test winding within the zero
phase sequence sensor, test by injecting test current in the test winding,
as long as the sensor is not differentially connected with another sensor.
Such systems are typically used with fused switch systems, but are
occassionally used with circuit breaker systems where the internal
breaker GF protection system is not used. In this case, a primary current
injection test method need not be used. The test is a self test that uses a
feature integral to the unit. If instructions are not provided, use the
technique in step 3 below.

3. For systems involving multiple sources or multiple levels of ground fault
protection, perform the following pickup tests using primary current
injection techniques. These tests shall be performed on each
independent bus, with test current applied from each possible source.
Example: If a power system consists of a Main, Tie, Main, and one
generator breaker on one side, this system would contain three
independent buses: the bus between the first Main and Tie; the busbetween the Tie and the second Main; and the bus (or conductors)
between the generator circuit breaker and generator. Test current would
be injected on the source side of each Main and from the generator
terminals. A grounding test lead would then be connected between each
of the defined bus locations and ground.
Check the manufacturers records for special testing procedures that
would be applicable for the particular system being tested.
(a) Verify that the relay does not operate at 90 percent of the pickup setting.
(b) Verify that pickup is less than 125 percent of setting, or 1200 amperes,
whichever is smaller.
4. For summation type systems utilizing phase and neutral current
transformers, verify that polarities are correct by applying current to each
phase-neutral current transformer pair. This test also applies to molded-case breakers using an external neutral current transformer.
(a) The relay should operate when the current direction is the same
relative to polarity marks in the two current transformers.
(b) The relay should not operate when the current direction is opposite
relative to polarity marks in the two current transformers.
5. Verify non-tripping activity by applying primary current injection testing
techniques as in number 2 above. Current setting for this test shall be
above 125 of the relay pickup setting. The test cable would be connected
between a phase conductor and the Neutral for that section of the gear.
This test shall be repeated for each condition as was determined in
number 2 above.
6. Verify that zone selective interlock systems are operating correctly.
Source breakers to an independent bus should receive a restraint signalwhen a ground fault is detected by a lower stream device. Complex
systems having multiple sources and tie breakers should operate in a
logical manner as is determined by the power system involved.
Example: For a Main, Tie, Main system, a restraint signal emanating from
a feeder breaker should not restrain the Main breaker on the opposite
side, unless that Main is the only means of protecting the bus to which
that feeder breaker is connected.
Since there are many different types of Ground Fault systemsElegant,
Non-Elegant, relayed tie, or non-relayed tieit is not practical to set down
one rule of operation. Each system must be evaluated on its own merit,
and a logical operation must be determined for each. It is suggested that
the project engineer be consulted in determining the correct operation.
C. Optional Tests
1. Measure the insulation resistance of the control wiring in accordance with
Table 2 on page 59. Do not perform tests on wir ing connected to solid-
state relays.
2. Measure the time delay of the relay at 150 percent or greater of pickup.
Verify operability of I2t function, if being used, of the ground fault trip device.
3. Verify reduced control voltage tripping capability: 55 percent for ac systems.

NOTE: All equipment shall be assured to be complete
and of acceptable quality. Inspection and testing of all applicable wiring and
equipment must conform to Article 517 of the National Electrical Code (NEC)
and Article 99 of the National Fire Protection Association (NFPA).
A. Visual and Mechanical Inspection
1. Perform a functional check of all equipment in the area.
2. Inspect all equipment in the area for physical damage such as
cracked meters or scratches. Any physical or electrical defect must be
recorded and discussed with the appropriate people at the job site. If the
damage appears to have occurred at the job site, note this on your report.
3. Inspect the room ground and the patient reference ground if installed.
4. Remove the stainless steel trim and the circuit breaker dead front.
Examine the branch circuit wiring.
5. Verify that the proper breaker identification is on the circuit schedule.
6. Examine the receptacles, ground jacks, lights, switches, and
miscellaneous electrical equipment for compliance to applicable
electrical codes.
B. Electrical Tests
1. Measure line-to-line and line-to-ground voltage with an ac voltmeter and
record the voltage on the data sheet.
2. Measure the leakage current with an ac microammeter that is capable of
being accurate within 3%. Record the value to three significant figures.
Measure the current between L1 and ground and L2 and ground.
NOTE: Before taking current measurements, verify that no phase
conductor is at ground potential.
3. Use the following formulas to determine the individual line impedance
based on the values calculated in step 2 and line-to-line voltage
measurement:
Line impedance measurements will include all receptacles, but are not
required to include lighting fixtures or components of fixtures. All
electrical equipment connected to the isolated power system must be
unplugged, and permanently installed equipment must be switched off.
For isolation panels with branch-circuit interlock (x-ray panels), branch
circuits must be measured individually. Record the circuit with the lowestcalculated impedance as the system impedance.
For panels in which a combination of circuits may be energized (PLC
laser panels), measure branch circuits individually; energize the
combination of circuits that contributes the highest amount of leakage
current. This value is used to calculate the system impedance.
If a line impedance is below 200,000 ohms (NFPA-99 1996, 3-3.2.2.2),
the probable cause should be determined. If you cannot correct the
problem at this time, you must note it on the report.
