2. Make sure the bucholze realy is full with oil no inert
gas is there if there then purge the same.
3. Check the record the Reading of OT & WT
4. Check manualy for any leakage from any part of the
transformer.
5. Check for any abnormal heating & noice in transformer.


Quarterly.

1. Check & change the silica gel of the breather .
2. Check teh Safety function tripping of HT breaker related
to transformer. ( tripping point of OT , WT & Tranfomer )

Annualy.

1. Check & fillter the Trasformer oil
2. with complete shut down take the reading of insulation
resistance of the transformer winding.
3. Open & check the condition of transformer HT & LT
bushing for any cracks or damage.
4. Chceck the condition of the earthing pit & take the
earthing resistance value for all the earthing pit (
Neutral & Body earth )

Do the same as directed & have a trouble free operation of
the transformer for a long period of time

by using pump duty, how we will can calculate the motor duty(KW)? is there any standard or formula.
