  • CP RC - Resonance circuit for GIS testing - OMICRON

    High-voltage testing with GIS resonance circuit. For HV testing OMICRON’s CPC 100 + CP RC are directly connected to the voltage transformer of the GIS, forming a resonance circuit. This reinforced “Power VT” is an integrated part of the GIS. So the need for draining and refilling any SF6 gas is eliminated.
