Engineering Principles of Partial Discharge Tester

When partial discharge occurs under the test voltage, the pulse current is generated through the coupling capacitor Ck, and the pulse signal is picked up by the input unit. The discharge pulse is displayed on the scan baseline, and it is also sent to the pulse peak table (logarithmic table) to display its peak value. The time window unit controls the working time of the pulse peak meter in each cycle of the test voltage, and highlights the display on the display screen during this period, and the width and position can be changed, which further strengthens the anti-interference ability.
The partial discharge tester is a new type of instrument developed and produced. The instrument has the advantages of high sensitivity, large dynamic range of the amplifier system, wide range of tested samples, and easy operation. And it adopts advanced anti-interference components and unique door display circuit, which has strong anti-interference ability, and has four high-frequency elliptical scans, which are suitable for type, factory test, new product development test of high-voltage products, motors, transformers, cables, Bushings, capacitors, transformers, arresters, switches and other high-voltage electrical bureaus
Quantitative testing of partial discharges. It can be used on-site by manufacturing plants, scientific research departments and power departments.
