This protection relay tester generates ring waves at 100 Khz and 1 Mhz. This phenomenon is representative of switching actions in HV/MV open air stations, and is particularly related to the switching of HV busbars. We also carry the CDN required to meet the ANSI/IEEE C37.90.1.s and IEC 61000-4-18 specifications.
