Diagnostic of Silicon Carbide Surge Arresters of Substation

2009-12-7 · Abstract: - This paper presents the results of a research project aiming the diagnostic of the silicon carbide surge arresters. These surge arresters are being gradually replaced by the gapless zinc oxide ones, therefore, it is very important to select the surge arresters that are more degraded in order to avoid failures in the field. Tests

Appliion Considerations for Gapped Silicon-Carbide

While the gapped silicon-carbide arrester designs have had a good service history, utilities are continuing to evaluate their overvoltage protection needs, in particular at loions that are currently protected by gapped silicon-carbide arresters. Once they identify loions and types of SiC arresters, they need to
