ADVERSE EFFECTS DUE TO FAULTS
Severe hot-spots
Oil heating
Winding deformation
Damage to clamping structure
Core damage
Explosion

MAGNETIC BALANCE TEST
Carried out on three phase transformers
Energize one of the phases with a voltage lower than rated voltage
Keeping all the other phases open-circuit
Compare voltage of this winding with open circuited winding
A fault in the winding can be detected by the induced voltage variation

BUCHHOLZ RELAY
Gas actuated relay
Used in oil immersed transformers having a voltage rating more than 500 KVA
