Handheld Multifunctional Partial Discharge Detection Equipment PD Tester is an instrument used to detect partial discharge phenomena in electrical equipment. Partial discharge refers to the phenomenon of partial discharge in insulation materials caused by the electric field strength exceeding its breakdown strength, which may cause damage to the insulation material of the equipment, thereby affecting the safety and reliability of the equipment.The partial discharge detector can monitor the partial discharge activity in the equipment and evaluate the insulation status of the equipment by analyzing data.
