We are using MWD-10 type SVL’s in the single point bonding link boxes in one of our HV cable project. In our contract with client , there is a test specified as “SVL characteristic” . Our understanding for this test is to be determined by applying DC voltage to the SVL and measure the reference current( Iref.) . In other words, it is to determine the reference voltage.And compare with the Uc.
We checked attached document, but did not find relation or formula between the max continuous operating voltage and reference voltage. So;
MWD-10 type SVL , Urated = 12,5kV , Uc=10kV and Iref =2,2mA specified on table 4 (in pg 17) for MWD arresters. The question is what is the ref. voltage for MWD-10 arresters ?
