Case Application of Live Detection Technology in Measurement of Partial Discharge of High-voltage Switchgear
This essay briefly clarifies the currently prevailing technologies for partial discharge live detection of high-volt-age switchgear including transient ground voltage detection,ultrasonic detection,and ultra-high frequency detection.It then reports a real case of applying partial discharge live detection technology to handling surface discharge in the contact box of an actual high-voltage switchbox,and verifies effectiveness and importance of live detection in maintenance work.
