This instrument features high detection sensitivity, wide coverage of sample capacitance, broad applicability to various test objects, complete input units (detection impedances), and multiple frequency band combinations (nine types). After proper calibration, it can directly read the discharge quantity of discharge pulses. Both analog and digital meters display simultaneously, and the analog meter can be conveniently switched between logarithmic or linear scale as needed. This instrument is a widely used practical partial discharge testing device in power departments, manufacturing companies, and research institutes.
