  • High Voltage Gas Insulted Switchgear (GIS) Field Testing

    Sep 18, 2019DC voltage withstand testing is not recommended on a completed GIS. However, it may be necessary to perform a DC voltage withstand test on power cables connected to a GIS. these test voltages would, by necessity, be applied from the end of the cable opposite to that of the GIS, therefore subjecting a small portion of the GIS to the DC voltage.
