Answer Posted / kiran
Daily check up
1)Oil level in conservator tank (Main and OLTC)
2)Oil leakages if any
3)Counter rteading of OLTC
4)Sound of Transformer
5)Hourly reading
Querterly Maint.
1)Cleaning of Transformer
2)Note down of Maximum temp of HV LV Wdg. & LV Wdg.
3)Checking of OLTC mechanisum Step by step
4)Tighting of HV & LV connection
5)Checking of gas collection in Bucholz relay, cleaning of
glass cover
6)Operation of cooling fan in manually,remote and auto mode
Yearly Maint: All above quarterly maint point plus
