Partial Discharges in Electrical Insulation

Power cable outputs Power cable or bus infeed 3 phase HV busses supported by insulating boards Potential transformers (PTs) and current transformers (CTs) to measure V and I Switchgear composed of cells (cubicles), usually each with a circuit breaker (infeed or output). The HV bus connects all the cells togetherMegger Test : Working, Construction and Safety MeasuresMegger Test for Cables. Insulation resistance test for cable using megger is a continuity test, where the power of the circuit is off. For example, if the cable is of the capacity of 5Amps, we can send current less than or equal to 5Amps and not more than that. If we send more than 5Amps this may cause the failure of the cable.Megger Insulation Resistance TestFigure 2 Typical Megger test instrument hook-up to measure insulation resistance. The generator can be hand-cranked or line-operated to develop a high DC voltage which causes a small current through and over surfaces of the insulation being tested (Fig. 2).This current (usually at an applied voltage of 500 volts or more) is measured by the ohmmeter, which has an indicating scale.
