Transformer Protection For Different Types of TransformersCommon Types of Transformer ProtectionOverheating Protection in TransformersOvercurrent Protection in TransformerDifferential Protection of TransformerRestricted Earth Fault ProtectionBuchholz (Gas Detection) RelayOver-fluxing ProtectionA very high fault current can flow when a fault occurs at the transformer bushing. In that case, the fault needs to be cleared as soon as possible. The reach of a particular protection device should be only limited to the zone of the transformer, which means if any ground fault occurs in a different location, the relay allocated for that zone shoul...See more on circuitdigest ABB Group
Transformer protection relays are used for protection, control, measurement and supervision of power transformers.
