Voltage Withstand Test (GIS)

Voltage withstand test voltages are primarily sinusoidal AC voltages above rated voltage. Originally, this dielectric test was a go/no-go test, where the test object either passed the test or it broke down electrically. Later, more sophisticated diagnostic tools were introduced. Today, the parallel measurement of partial discharges has become an indispensable tool. The voltage withstand test can be performed more safely and more detailed information about the insulation condition can be gathered with a parallel PD measurement.

High Voltage Resonance Test System

This test system is designed to form a resonance circuit with the voltage transformer (VT) of the GIS, which is then used as a convenient interface for the high-voltage tests, e.g. during commissioning or after expansions. The VT of your GIS must fulfill certain performance requirements regarding the cross-section of the secondary winding wire and the insulation of the secondary winding for this system to work. Siemens call such VTs “Power VTs”.
