4 FAQs about Relationship between inverter discharge and voltage

Can overvoltage cause partial discharge?

Resulting overvoltages can cause partial discharges (PD) if the critical voltage inside the insulation system is exceeded. This applies in particular to the winding insulation, which is predicted to be the weakest point. The critical voltage can be determined using the Paschen curve.

What affects PdIV/rpdiv (repetitive partial discharge inception voltage)?

In the following sections, the effect of pressure, relative humidity (RH), and temperature on PDIV/RPDIV (repetitive partial discharge inception voltage) are gathered. The RPDIV is the minimum peak-to-peak impulse voltage at which more than five PD pulses occur on ten voltage impulses of the same polarity according to IEC 60034-18-41 .

Does inverter output change at the moment of voltage drop?

From Fig. 19 c), it can be seen that the inverter output instantaneous active and reactive power is changed at the moment of voltage drop. However, only reactive power is changed in steady-state, and active power is almost not affected. This experiment verifies the analysis in Section 4.3.2.

What is partial discharge inception voltage (PdIV)?

The partial discharge inception voltage (PDIV) is not only depending on the amplitude of the electric field but also on the timely sequence. Modeling partial discharge processes is an instrument to predict the electrical load on insulation systems and to evaluate possible new design criteria for insulation systems.
