Abstract

According to the results of the field return voltage measurement（RVM） technology

the precautions and influencing factors on the RVM technology are described. Emphases are put on the on-the-spot factors influencing RVM results

such as ambient temperature

residual charges

and strong electromagnetic field

and the countermeasures against the influences of these factors. The purpose of this study is to improve the accuracy of the RVM technology for assessing insulation condition of transformers.
