JF-2008 Type Partial Discharge DetectorDetailed product description：

The JF-2008 partial discharge detector has high detection sensitivity, a wide coverage range of sample capacitance, a wide range of applicable test samples, complete input units (detection impedance), and multiple frequency band combinations (nine types). After appropriate calibration, the partial discharge detector can directly read the discharge amount of the discharge pulse. The pointer type meter and digital meter display simultaneously, and the pointer type meter can conveniently select logarithmic or linear scale indication as needed. Widely applicable for measuring partial discharge of various high-voltage electrical products such as transformers, transformers, high-voltage switches, zinc oxide lightning arresters, power cables, etc., conducting type tests on products, and supervising insulation operation. This instrument is a practical partial discharge testing device widely used by power departments, manufacturers, and research institutes.
