Abstract: High-voltage dielectric loss test is an effective method to judge electrical equipment insulation state. Analysis was made to the abnormal dielectric loss test value of DC 500 kV electronic voltage and the causes of abnormal test value were found, the corresponding improvement measures given. The needed cautions were raised in electronic transformer dielectric loss test.
Key words: DC electronic voltage transformer; dielectric loss test; deviation
