Abstract

Differential protection is provided in the electrical power transformer which are higher rated. This type of protection can detect internal faults in the transformer. However, it cannot prevent external faults from occurring in the transformer. If a short circuit is detected in the bushings, then the Buchholz relay cannot effectively cover it. In addition to detecting internal faults in a transformer, Buchholz relays can also be utilized to detect other types of faults. But, the differential protection scheme is faster than the Buchholz relay. This ensures that the relays can respond to the faults that occur in the side of the transformer that's in differential protection zone.
