| 摘要 |
The present invention relates to a unit comprising a plurality of varistors, specifically for the purposes of overvoltage protection in synchronous generator exciter discharge systems. Compared with existing varistor units, the unit of the invention is able to be transported more efficiently, is more compact, and requires fewer individual varistor units to be placed in a synchronous generator exciter discharge system while still achieving the required thermal and electrical ratings to perform to the desired requirements. |
