Partial discharge testing relies on the accurate detection of four key metrics: partial discharge
inception voltage (PDIV), repetitive partial discharge inception voltage (RPDIV), partial discharge
extinction voltage (PDEV), and repetitive partial discharge extinction voltage (RPDEV).
NOTE: The RPDIV and RPDEV voltages are determined by using data from multiple previous
surge pulses and comparing them to the current pulse.
If the voltage step is too high, you might step over the point where PD events first occur, so it is important
that voltage ramping occur in controlled and slowly-increasing steps to obtain inception voltages.
Likewise, extinction voltages should be acquired using slowly decreasing steps. Test time will increase
slightly, but you will obtain more accurate results.
From the
User Settings
screen, select a fast ramp rate of no more than 50 volts and a slow ramp
rate of no more than 10 volts to increase repeatability of RPDIV and RPDEV measurements.
