Answer Posted / venkat iyer
1) Differential Protection
2) Winding Temp
3) oil Temp
4) Under Voltage and over voltage
5) Under Frequncy Protection for Higher Range of Power
Transformers
6) Bucholz Relay Protection for oil cooled transformers (to
detect incipient fault)
7) Pressure reilef Valve for oil cooled transformers
8) Restricted Earth Fault Protection
9) Overload, short circuit and earth fault protection
10) Protection against fire in case of oil cooled
transformers
11) directional protection
