[0002] Partial discharge tester, also known as partial discharge test instrument, is a device used for partial discharge detection. Its working principle is mainly based on high-frequency pulse current measurement method. When electrical equipment generates partial discharge under test voltage, the discharge pulse signal is sent to the input unit through the coupling capacitor, and the input unit picks up the pulse signal, and then amplified by the low-noise preamplifier and the filter amplifier selects the required frequency band;
