Abstract:Electronic transformers compared with the traditional electromagnetic transformers, the structure and working principle have undergone great changes. It’s necessary to do site calibrationto ensure the electronic transformer in the power system in a safe and reliable operation. In this paper, the method of on-site polarity checkanderror test of electronic transformer is analyzed and discussed in the process of intervention and acceptance of Hongji 220kV substation.
