• SF6 C.B.
• AIR BLAST C.B.
• OIL C.B.
– MIN. O.C.B.
– BULK O.C.B.
• VACUUM C.B.

11. CURRENT TRANSFORMERSCURRENT TRANSFORMERS
• MEASURE CURRENT
• PROVIDE THE PRE-DECODED
FRACTION OF THE PRIMARY
CURRENT PASSING THROUGH
THE LINE

12. PROTECTIVE RELAYS
PROTECTIVE RELAYS IS AN ELECTRICAL DEVICE CONNECTED
BETWEEN THE MAIN CIRCUIT AND CIRCUIT BREAKER THAT
DETECTS FAULTS
WORKING OF PROTECTIVE RELAY

14. INSULATOR
• PROVIDE MECHANICAL STENGTH
• PROVIDES INSULATION TO CONDUCTORS FROM THE
GROUND SO THAT CURRENTS FROM CONDUCTORS DO NOT
FLOW TO EARTH THROUGH SUPPORTS
• THE INSULATORS PROVIDE NECESSARY INSULATION
BETWEEN LINE CONDUCTORS AND SUPPORTS, THUS
PREVENT ANY LEAKAGE CURRENT FROM CONDUCTORS TO
EARTH
• TYPE OF INSULATORS:
• Strain Type
• Pin Type
• Suspension Type

15. TEMPRATURE INDICATORSILICA GEL BREATHER

16. POWER TRANSFORMER
• TRANSFERS THE ELECTRIC ENERGY FROM ONE
CIRCUIT TO ANOTHER
• WORKS ON HIGH VOLTAGE

17. Important Terms
Tripping – Power goes due to over load . It is for the
protection of components.
Shut down – Power is cut due to maintenance in
progress. It is done manually.
Break down – Power goes due to any fault in the
line. When fault is removed , power is back.
Rosting – Power is cut deliberately on order of
higher authority due to shortage of power.
