1 Introduction
to CT and PT
Instrument transformers (ITs) are
designed to transform voltage or current from the high values in the
transmission and distribution systems to the low values that can be utilized by
low-voltage metering devices. There are three primary applications for which
ITs are used: metering (for energy billing and transaction purposes);
protection control (for system protection and protective relaying purposes);
and load survey (for economic management of industrial loads). Depending on the
requirements for those applications, the IT design and construction can be
quite different. Generally, the metering ITs require high accuracy in the range
of normal operating voltage and current. Instrument transformers are the most
common and economical way to detect a disturbance. Typical output levels of
instrument transformers are 1-5 amperes and 115-120 volts for CTs and VTs,
respectively.

2. Types of insulation
There are
different types of insulation are used in instrument transformers according to
their dielectric breakdown strength, The primary and
secondary coils of a transformer are the key components in performing its basic
function of transforming voltage and current. Materials are used to insulate
the primary and secondary coils. In transformers, in addition to the primary
and secondary coils, there are several other important components and
accessories. The insulating material is one of the most critical components of
a transformer. Sufficient insulation between different active parts of the
transformer is necessary for its safe operation.
3. Type of Core
The transformer core is an iron block that acts as a
path for the flow of magnetic flux. Thus, the transformer core forms the magnetic circuit
of the transformer. It is used to confine the magnetic flux to a definite path.
The transformer core acts as the housing
for the primary and secondary windings of the transformer in addition to providing a path for the magnetic
flux. As we know, a transformer works on the principle of mutual
inductance. According to this principle, the
magnetic flux produced by one winding (primary winding) links to another
winding (secondary winding) to produce a transformed voltage or current. These
two windings are electrically isolated and magnetically coupled to each other.
It is also known that the opposition in the flow of magnetic flux is referred
to as magnetic reluctance. It will
cause a reduction in the amount of magnetic flux due to the high reluctance of
air or non-ferrous material.
4. Type of Winding
Transformer winding includes
different turns of copper coil bundles where every bundle is connected to form
a winding. Windings mainly depend on the input-output supply otherwise on the
range of voltage. Transformer winding is available in two types, i.e.
primary winding and secondary winding. Transformer winding operation is, that
the primary winding gets electrical energy from the source whereas secondary
winding transmits electrical energy to the load. Transformer winding
materials are aluminium and copper which are the most frequently used
conductors in transformer windings.

5. Molding and Finishing
Epoxy resin:- Hardener,
silica powder, colour paste and plasticizer are mixed together to make insulation

7. Conclusion
CT
reduces the large current to a safer and measurable level and PT reduces the
high voltage to a safer and measurable level, Current transformer is a voltage
step-up and current step-down transformer and the Voltage transformer is a
voltage step-down and current step-up transformer.
