HDE HiSat Surge Arrester Tester
The Hi-Test® HiSat MOV Surge Arrester and Leakage Testers allow for the non-destructive testing of de-energized surge arresters for non-visible internal breakdown. These self-contained units are lightweight and portable for both shop and field use. The HiSat applies voltage across the arrester and indicates the breakover/conduction point of the arrester. It will determine if an arrester is conducting at lower voltages than specified or not conducting at all. Because of new arrester technology, the testers will not properly test gap or hybrid MOV/GAP type arresters such as Hubbell® Optima or Cooper VariGAP®.
