摘要
结合现场试验,详细分析了回复电压试验的注意事项及影响因素,重点阐述和剖析了环境温度、残余电荷、强电磁场等现场因素对恢复电压测试法(return voltage measurement,RVM)测量结果的影响,以及消除或减弱这些因素影响的方法,以提高RVM方法对变压器绝缘优劣评估的准确性。
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.
