measure the discharge level of electrical equipment through the following
indicators:
Partial discharge intensity detection: By measuring the discharge signal within a
power frequency period, the intensity of partial discharge is characterized
according to the maximum value (dB) in the discharge pulse sequence.
Partial discharge frequency detection: The device measures the discharge
signal within a power frequency period, extracts discharge pulses and
characterizes the frequency of partial discharges according to the number of
discharge pulses.
