High Voltage Testing Lab
High voltage test facility is available in the department
with the generator set up of 200 kV AC, 280 kV DC and 280
kV impulse voltages. Transformer oil testing facility up to
80 kV is established.
Testing facility has following set of equipments:
Capacitor divider rated for 200kV, 100pF (KVTEK).
H.W.S. Test System Bangalore make High Voltage Test
Transformers 140KV along with control panel.
Sphere gaps, Resistors, capacitors, diodes.
Connecting rods, insulating rods, connecting cups.
As transformer oil deteriorates through aging and moisture
ingress, transformer oil should, depending on economics,
transformer duty and other factors, be tested periodically.
Electric utility companies have a vested interest in periodic oil
testing because transformers represent a large proportion of their
total assets.
Through such testing, transformers' life can be substantially
increased, thus delaying new investment of replacement
transformer assets.

Transformer Oil Testing Lab
Transformer oil, a type of insulating and cooling oil used
in transformers and other electrical equipment, needs to
be tested periodically to ensure that it is still fit for purpose. This is
because it tends to deteriorate over time. Testing sequences and
procedures are defined by various international standards, many of
them set by ASTM. Transformer oil testing consists of
measuring breakdown voltage and other physical and chemical
properties of samples of the oil, either in a laboratory or using
portable test equipment on-site.
Why testing:
The transformer oil (insulation oil) of voltage transformers and
current transformers fulfills the purpose of insulating as well as
cooling.
Thus, the dielectric quality of transformer oil is essential to
secure operation of a transformer.
Power Quality Analyzer
Power Quality Analyzer EN50160 Mode:
It is available on Ver1.30 or later. When this mode is selected,
the measurement function for EN50160 is added to the normal

Field Plotter Hive Volta
The use of electrolytic devices for this purpose is well known. These
devices employ a pair of electrodes which are immersed into
an electrolytic solution contained in a tank. Successive null point
readings, i.e. equipotential points, are taken at various points between
the electrodes.

DC Machines
A DC motor is an electric motor that runs on direct current power. In
an electric motor, the operation is dependent upon simple
electromagnetism. A current-carrying conductor generates a
magnetic field, when this is then placed in an external magnetic field,
it will encounter a force proportional to the current in the conductor
and to the strength of the external magnetic field. It is a device which
converts electrical energy to mechanical energy. It works on the fact
that a current-carrying conductor placed in a magnetic field
experiences a force which causes it to rotate with respect to its
original position.

Single Phase and Three Phase Transformer
A single-phase or three-phase transformer is an electrical
device that accepts single-phase AC power and outputs
single-phase AC. This is used in the distribution of power in
non-urban areas as the overall demand and costs involved are
lower than the 3-phase distribution transformer. They are
used as a step-down transformer to decrease the home
voltage to a suitable value without a change in frequency. For
this reason, it is commonly used electrical power appliance at
residences.

Motor Generator Set
A motor generator (M-G) set refers to a composite device consisting
of a motor and a generator mechanically coupled through the common
shaft. Practically a motor generator set is a system where a motor and
a generator are connected or rather placed in a single circuit. It is a
device used to convert electrical power from one form to another.
That is mainly it converts electrical power to any other type of power.

Three Phase Slip Ring Induction Motor
The slip ring induction motor could be used for industrial wires
where variable speed and high starting torque are prime
requirements. The stator of slip ring induction motor is very much
the same as that of the squirrel cage induction motor, but the
construction of its rotor is very much different. Stator winding can
be either star or delta connected depending upon the design.
Induction with this type of rotor is having three phase double layer
distributed windings. Insulated enameled copper wires are used for
coils.

Power System Protection Schemes
IDMT Relay (Inverse Definite Minimum Time Relay) is
protection relay. They are used on transmission lines to see to that the
line current doesn't exceed safe values and if it does, triggers the circuit
breaker. IDMT means inverse definite minimum time.
Use of IDMT relay:
The relay will not operate when the value of current is less than the
pick value. The relay is used for the protection of the distribution lines.
The inverse time relay is of three types. The relay whose operating
time is approximately proportional to the fault current is known as
the IDMT relay.

ARM Cortex M3 Evaluation Board
The ARM Cortex-M3 is a general purpose 32-bit microprocessor,
which offers high performance and very low power consumption. The
Cortex-M3 offers many new features, including a Thumb-2 instruction
set, low interrupt latency, hardware divide, interruptible / continuable

Applications of Cortex M3 processors (Industrial
Relevance)
Low-cost micro controllers: The Cortex-M3 processor is ideally
suited for low-cost micro controllers, which are commonly used
in consumer products, from toys to electrical appliances. It is a
highly competitive market due to the many well-known 8-bit and
16-bit micro controller products on the market. Its lower power,
high performance, and ease-of use advantages enable embedded
developers to migrate to 32-bit systems and develop products

Digital Trainer Kit
Digital Trainer Kits provided with two different levels of
regulated power supply [-5v to 0v to +5v] & [-15v to 0v to
+15v]. It is used for the verification of Logic gates or can
also be used for analyzing digital circuits. Both Logic
circuits and digital circuits are made up of integrated
circuits (IC’s) of 74XX TTL family. It can be used for
rigging- up complex circuits using two or more numbers of
IC’s at a time. Trainer kits provide needful flexibility for
conducting experiments.

DC Power Supply (Regulated)
Electronic circuits needing stable DC power supply of
different levels, for example biasing requirements of
transistor amplifier or to study the device characteristics
one way require variable DC in such cases Knob can be
operated to assign different levels of the voltage. Either
due to source variation or load variation the voltage level
may get affected therefore there is need of regulated DC
power supply.
