Online adaptive protection can automatically identify and diagnose the fault type

Change caused by the regulator tap the TA secondary current mismatch, seriously affecting the accuracy and reliability of the differential protection. Online adaptive protection can automatically identify and diagnose the fault type and automatically  mcb circuit breaker  and characteristics of protective action. As adaptive protection hardware foundation, the rapid development of computer systems makes adaptation more extensive  power transformers  prospect theory. In-depth understanding of transformer differential protection based on an adaptive principle and criteria currently used inrush current is proposed by combining the new voltage switching principle and the second harmonic restraint combination of complex criteria.
