TRANSFORMATION
 CORE AND WINDING
 CONSERVATER
 BREATHER
 OIL
 BUCHKOLZ RELAY

7. CIRCUIT BREAKER
Oil circuit breakerAir-blast circuit breaker
Sulpar hexafluoride circuit breaker (SF6)Vacuum circuit breakers

8. CB AND RELAY
 RELAY.
1. Actuator mechanism -
forces the contacts
together or apart
2. Contacts - Allow current
when touching and
break the current when
moved apart
3. Terminals
4. Bimetallic strip.
5. Calibration screw -
allows the manufacturer
to precisely adjust the
trip current of the device
after assembly.
6. Solenoid
7. Arc divider/extinguisher

9. BUSBAR ,LA,INSULATOR
 SAME VOLTAGE
