Causes behind the failure of the Distribution Transformer
Lavanya
Chaudhari, SE (Electrical), Div. B
lavanyachaudhari2004@gmail.com
India is a developing country, and
electricity plays a vital role in the development of India. The generation of
electric power is essential, but the distribution of electric power to provide
reliable power cannot be ignored. In the distribution system, the distribution
transformer plays an important role. The study involves reasons for failures
due to internal construction features of the distribution transformer &
external parameters attributing to the failure of the distribution transformer,
respectively.
The main parts of the distribution
transformer are the core, winding, transformer oil, main tank, breather,
cooling, radiator, and bushings. A laminated core is a magnetic material in
which the transformer winding is wound, which provides necessary magnetic
circuits. This is dipped in transformer oil, which is stored in the main tank.
Radiators are used in the transformer to cool the transformer oil and reduce
the winding temperature under loading conditions on the top of the transformer
tank.
Buchholz relay acts as a protective
device used to connect the conservator tank with the main tank. The bushing is
an insulator put on the top of the transformer tank through which the external
three-core cable is connected to the transformer and provides step-down voltage
through four-core cables (RYBN).
Transformer
Core Failure: The transformer core is designed to
provide a path for the magnetic field to flow around, which is necessary to
induce the voltage between the two windings. The core acts as a support to the
winding in the transformer. It also provides a low reluctance path to the flow
of magnetic flux. The function of the core is to concentrate the magnetic flux;
if a fault occurs in the core, it directly affects the transformer windings. It
gets damaged due to some reasons like low maintenance, old oil, and corrosion.
Suppose the lamination of the core gets damaged. In that case, it will increase
the eddy current, which is directly proportional to thermal heat & due to
this thermal heat, the distribution transformer gets damaged.
Transformers
Winding Failure: Transformers have mainly
two types of winding, Primary winding and Secondary winding. The primary
winding is used to take power from the source, and the secondary winding is
used to transfer changed voltage to the load. The windings suffer from three
types of stresses during transferring high voltage/low current are dielectric
stress, thermal stress, and mechanical stress. The faults that occur in the
winding due to these stresses cause failure winding and the breaking of winding
or burn out.
Transformer
Tank Failure: The transformer tank contains the
transformer oil and protects the core & windings from external conditions
like lightning, dust, rain, etc. Because of corrosion, environmental stress,
high humidity, etc. cracks in the wall of tanks occur, leading to leakage of oil,
which finally results in a reduction in oil quantity. From this leakage &
reduction of oil, there is a reduction of insulation in the winding. Due to
this, the temperature of the distribution transformer increases during the
operation and may damage the transformer.
Conservator
Tank Failure: This is a cylindrical tank that is mounted on
the top of the main transformer tank. The conservator tank is half-filled with
transformer oil. When the transformer’s load is increased, the temperature of
oil also increases then the conservator tank absorbs the volume of increased
oil in its upper space. The conservator tank’s primary function is to provide
sufficient space for spreading the oil inside the transformer (known as the
breathing of the transformer). If there is any fault in the conservator tank,
it cannot absorb the increased oil volume in its free upper space, and the tank
will burst due to high oil pressure at full loading conditions.
Buchholz
Relay Failure: Buchholz relay acted as a
protective device and is used to sense the faults due to high temperature
inside the transformer, and it is connected between the main tank and
conservator tank. It is a type of gas and oil-activated relay. When the
temperature of the main tank’s oil is increased, the oil evaporates in the form
of gas. When the gases are produced in large amounts, the Buchholz relay
detects the failure and gives the alarm. The transformer is disconnected from
the main supply for maintenance. If the Buchholz relay fails, it will not
detect the fault, then gas moves upward, and the alarm doesn’t work due to this
transformer going into a danger zone, and the transformer will get damaged due
to high oil pressure.
Explosion
Vent Failure: The purpose of the explosion vent
in a transformer is to prevent damage to the transformer tank by releasing any
excessive pressure generated inside the transformer. It is also a transformer’s
safety device, which protects the transformer tank from the high consequences
of the high-pressure gases induced in the transformer. It allows the gas to
escape by puncturing the diaphragm. The explosion vent’s failure will be why a
transformer fails during the system’s fault.
Breather
Failure: Whenever the transformer is under full
load condition, the transformer’s insulating oil gets heated, and the
temperature of the insulating oil increases, and thus the volume of the oil
increases. As the oil volume is increased, the air above the oil level in the
conservator tank will come out. The breather acts like an air filter for the
transformer and controls the moisture level inside the transformer. It will not
absorb moisture present in the air of the tank due to which moisture and dust
are added to the oil and that oil will lose its dielectric properties, and the
transformer will get damaged.
Radiator
Failure: The radiator is a collection of hollow
pipelines used to transfer thermal energy from one medium to another for
cooling. Radiators are used for cooling the transformer oil, which reduces the
winding temperature under loading conditions. The radiators are connected to
the transformer through the pipeline at the transformer’s upper and lower
sides. If radiators get damaged, it will not cool down the temperature of
transformer oil with the help of atmospheric air, due to which the temperature
of the oil will increase and may become the cause of failure.
Bushing
Failure: The bushing of the transformer is a type
of porcelain insulator put on the top of the transformer tank through which
connections are made to the external circuit. Bushings consist of a
current-carrying part of the conducting rod in the center, a porcelain cylinder
installed in a hole on the transformer cover, and insulation of the
current-carrying part. The primary failure mode of the bushing is a short
circuit. It may be due to material fault in the insulator or due to mechanical
damage. However, the cracks in the porcelain and water ingress inside the
insulation of the bushing may lead to this failure.
