Study on Condition Detection for the Varistor Based on the Response to Combination Wave
Yanming Li · Gaoya dianqi · 2004
In order to maintain operational reliability of low-voltage supply system and information system, it is very important to detect the varistor's condition timely and effectively. In this paper, several types of failure modes of varistor are concerned. According to the research of varistor's response to combination wave, it shows that the responses vary with the varistor's failure modes because of the difference in V-A characteristic. Based on the response, the kind of failure modes of varistor could be determined.
