high-voltageswitchgear Analysis for testing

High voltage (HV) Switchgear Risk assessment is the determination of quantitative or qualitative estimate of risk related to a well-defined situation and hazard. If you use switchgear you must assess the risks and manage them to ensure safe operation and minimise the risk of injury.

    Mar 20, 2021Therefore, if we use dc test voltage, we ensure that the dc test voltage is under root 2 (or 1.414) times the ac test voltage, so the value of the dc voltage is equal to the ac voltage peaks. For example, for a 1500-V-ac voltage, the equivalent dc voltage to produce the same amount of stress on the insulation would be 1500 x 1.414 or 2121 V dc.
