Power equipment testing method based on active compensation mutual inductor and three-phase source

The invention relates to a power equipment testing method based on active compensation transformers and a three-phase source, and the method comprises the steps: adding the active compensation currenttransformers at the output end of a three-phase source, and determining the number of active compensation current transformers according to the maximum on-load load load of a single-phase current ofthe three-phase source; connecting a primary side coil of the current transformer in series and then is connected in series with the standard meter, connecting the recorder and the three-phase source,and a secondary side coil of the current transformer with a device to be tested. According to the power equipment testing method based on the active compensation mutual inductor and the three-phase source, active compensation is carried out through the current mutual inductor, it is guaranteed that the primary side current and the secondary side current are consistent, the compensation circuit isadditionally arranged, erro
