脈沖電流法是當前普遍認可且廣泛使用的一種局部放電量測試方法,其結(jié)果是以pC為單位的視在放電量,屬于定量性質(zhì)的測量,能客觀反映電氣設(shè)備的絕緣狀態(tài)。

The pulse current method is currently a universally recognized and widely used partial discharge measurement method. The result is the apparent discharge in pC, which is a quantitative measurement and can objectively reflect the insulation state of electrical equipment.
The local on-line monitoring device adopts ultra-low power consumption design, strong anti-interference ability, and can be calibrated online; it also has a three-phase live display function, LED displays whether the switch cabinet is live, maintenance-free, low power consumption, verifiable phase and low phase voltage.
