Answer Posted / latika
For Power Transformer:-
1] Insulation test [P-N,S-N & P-S]- Yearly
2] BDV of Oil [top and bottom sample]- Yearly
3] Topping up of Oil if reqd.
4] Opening of all stud connentions cleaning of connectors,
washers, replacing damaged ones and reconnecting properly
both in HV and LV sides.
5] Conditioning the earth electrodes [ both body and neutral
earthings] i/c the continuty made by flats or copper wire,
tightening of joints if any, watering [weekly] in case of
hilly lands.
