Manual PD Tester

Product Introduction

Partial Discharge (PD) Tester is a new type of device developed by our company.Basically, it possesses the merits and functions of the above-mentioned two devices. It adopts a special interference distinguishing logical circuit, which can discriminates the accidental interference (The interference must exceed a limit and last at least 4 continuous test periods). Cooperating

with the time window, it can enhance the ability to discriminate and eliminate external interference. This device, combined with JZF-9 mini calibrator, is applicable to the operation and maintenance in the power system and workshops, where the equipment needs to be moved frequently and the interference is strong.

Product Features

• The convenient PD setting device, enable reading the partial discharge value directly on the interface.

• Pulse peak value meter sampling and digital voltmeter matching well with each other; high accuracy on measuring.

• The discharge quantity can be recorded (repeat rate n), matching up with other components, can get the relationship between q—n,n—ψ,q—ψ. ( q- discharge level, ψ phase angle ).

• Digital display, difffferent parameters are visible.

• Small volume&light weight, suitable for testing in power institutes or workshops.

• High sensitivity.

• Pioneer of logic interference detection device.

• Equipped with a particular anti-interference mode and the device can attenuate the interference greatly.

• High strength on anti-impulse.

• Equipped with the high frequency elliptic scan

• (inception power<1VA )

• Large dynamic range of amplifying system

• Diversifified combinations of frequency bands

• (9 kinds)
