Research on state evaluation of fast switching variable impedance energy saving transformer

In view of the difference between the new fast switching variable impedance energy-sav-ing transformer and the traditional transformer, the state evaluation method of the new transformer wasstudied. The principle and characteristics of fast switching variable impedance transformer were introduced,and the condition monitoring scheme of variable impedance transformer was designed. Fast switching condition monitoring method and transformer condition evaluation method were proposed respectively.A layer-by-layer discrimination method of discharge fault and overheating fault based on gas com-ponent ratio combination was proposed. The research results can provide reference for the condition monitoring and evaluation of the new variable impedance transformer.
