1)Differential protection (If transformer is more than 5
MVA :As per IS 2026)
2)Restricted earth fault protection
3)Stand by earth fault protection
4)O/C & E /F protection (if required)
5)Over flux (V/F)
Auxiliary protections
1)B' relay protection
2)PRV
3)Oil temp. high trip
4)Winding temperature high trip
5)OSR
Alarms:
1)Winding temp. high alarm
