| description | The invention discloses a capacitive coupling-based partial discharge data measurement TEV sensor system, which is characterized in that a coupling capacitor plate, an equipment shell and a switch grounding cabinet metal shell are connected in sequence, copper is laid on the side part of the coupling capacitor plate to form a metal layer, a filter capacitor C2, a coupling capacitor C3 and an output resistor R are welded, and all the components are integrated on one plate, the TEV sensor system can be coupled to transient voltage induced by partial discharge, the capacitor C1, the filter capacitor C2, the coupling capacitor C3 and the output resistor R form a sensor coupling circuit, the area of a PCB (printed circuit board) is reduced while measurement is realized, and the measurement precision is improved. The device can be conveniently installed in the hand-held partial discharge detection device, and miniaturization and integration of the device are realized.
