Fault Diagnosis of Power Transformer in Mine

open access: yesIOP Conference Series: Materials Science and Engineering, 2020
Abstract In view of the ambiguity of power system transformer faults in mines, the traditional gas analysis method cannot directly judge the possibility of fault occurrence based on gas concentration. A fault diagnosis method for mine transformers based on intuitionistic fuzzy Petri nets is proposed.
