DESCRIPTION
Direct measurement of Current in high voltage system is not possible because of insulation problem of measuring instruments. It is also not possible to use current flowing through the system directly for protection purpose due to its high value and high insulation problem. In such conditions Current Transformers are used.

BASIC FUNCTIONS OF CURENT TRANSFORMERS ARE
•	To reduce the line current to a value which is suitable for standard measuring instruments, relays etc.
•	To isolate the Measuring Instruments, Meters, Relays etc. from high voltage side of an installation.
•	To protect Measuring Instruments against short circuit currents.
•	To sense abnormalities in current & give current signals to protective relays to isolate the defective system.

FEATURES

The transformers are vacuum encapsulated in epoxy resin, which ensures faultless insulation. Incombustible high-class raw material, together with uniform cast resin bodies, gives the current transformers a high mechanical & electrical strength that requires no maintenance. It is advisable to protect the transformers from direct sunlight & access to dust.
