POWRE HOUSE

Power is supplied to the entire workshop with the help of two feeders north and south. If any fault occurs in any one of the two feeders, then total supply is given by the other feeders. The feeders take supply from HYDEL comes into HT panels of the power house. In the HT panel there are OCB’s and MCCB’s which trip down to off position in case of any fault. These OCB and MCCB work as protective devices. The power is step down as required by transformers of different ratings. The specification of the transformers are as follows:

Transformer no.                                                   Details of transformer

1                                                                                                                                           For 3.3KV incoming 11/3.3 KV, 750 KVA  installed on Oct 1969

2                                                                                                                                           For 3.3 KV incoming , 750 KVA installed on Oct 1961

3                                                                                                                                            For 500 KVA DG set 11/3.3KV , 1000 KVA installed on Oct 1961 , Reinstalled in 1997                                   

4                                                                                                                                           Disconnected from 11 KV supply 11/3.3KV ,1000 KVA

5                                                                                                                                           For auxiliary and office 3.3/.44KV , 500 KVA installed on Jan 1958

With the help of these transformers supply is converted into required voltage and is fed to the substation 1, 2, 3, 4, 5&6, hospital feeder, GM office , loco shed and colony feeder.

In cases of power break down there is a voluntary arrangement for power generation through a D.G set (diesel generator) of 2250 KW. One of its units is of 1750 KW and other is of 500 KW.

The specification of its two unit is as follows:
