Partial Discharge Meter with Built-In Oscilloscope performs measurement of partial discharges in pC and RIV in mV. The Partial Discharge Meter is featured with a built-in oscilloscope to display PD pulses on elliptical time base and window gating facility to mask unwanted noise. The Partial Discharge Meter has the facility to conduct balance mode PD detection to minimise the background noise. Partial Discharge Meter with Built-In Oscilloscope functions with a variable selective filter ranging from 600 kHz to 2400 kHz.
