NOTHING IS IMPOSSIBLE
WE CAN DO IT
LAYOUT OF 110/11KV SUBSTATION: CIRCUIT DIAGRAM: THEORY : 1. The 3 phase 3 wire 110 KV feeder is tapped and brought to the Gang operated (GO) switch. The GO switch consists of isolators connected in each phase of the 3 phase line. 2. From the isolator the 110KV line is brought to the 110 KV Bus bar through Circuit Breaker (CB). 3. From the 110KV Bus bar, the 110 KV line is fed to the HT side of the 110KV/11KV stepdown transformer through Isolator. The transformer steps down the voltage to 11KV. 4. In fig.1.2. two 110/11KV transformers are connected from the 110 KV bus bar and the LT side of the power transformers are connected to the common 11KV Bus through CB and Isolators. 5. From the 11KV Bus bar no of feeders are taken through isolator and CB. 6. Lighting arresters are provided for protection from lightning and current transformers for...
