| Abstract: | Measuring resistive current of metal oxide arrester according to the service voltage is important to check whether MOA is damped and to indicate service status of MOA.Author introduces basic principle of measuring resistive current of MOA by method of potential voltage transformer(PT),and provides results of some kinds of tests and evaluation criterion of MOA degradation.Finally,the author points out that measuring resistive current play an important role in improving insulation test and intensifying insulation supervision. |
