what are trouble functions of transformer?ex. prv
trip,oltc,oti,wti.explain detail.
Answer / srikanth_kalishetti@yahoo
1. PRV Trip :- The transformer inside when abnormal
pressure is build up the PRV Trip occurs.
2. OLTC :- It is the on-load tap changer. Through which tap-
changing of the transformer is done to lower or raise the
taps of the transformer.
3.OTI :- Oil temperature Indicator. It indicates the oil
temperature of the transformer.It gives alarm & later trips
the transformer when the set temperature is reached.
4. WTI:- Winding temperature Indicator. It indicates the
winding temperature of the transformer.It gives alarm &
later trips the transformer when the set temperature is
reached.
