HYG-2005 multicenter partial discharge tester is our newly designed and developed instrument. It keeps the strongpoint and function of former models, and on the advanced theory and IEC’s standard, the instrument is made with advanced circuit and technology, and corrected after continuous test. The instrument is designed more perfect, easier to use and reliable on the capability.

1、Measuring channels: 3 channels (Standard)

2、The scale of the tested electrical capacity

3、The permitted current when delicacy ratio is tested (Form 1)

Form 1  Check delicacy ratio and permitted input current value

4、Ellipse scan time base:

（1）Frequency 50（inner）、100、150、200、400HZ。

（2）Circumrotate: 30℃ is a shift, it can be circumrotated 360℃.

（3）Working method: ellipse——extend——beeline

（4）When it is high frequency, the basic ellipse can be adjusted to normal size from input voltage（10～250V）, its power is less than 1 Amp.

5、Display Unit

It adopts rectangle oscilloscope, there are buttons to adjust lighteness and focus.

    6、Magnifier

（1）Any of 3dB low frequency range fL

（2）Any of 3dB high frequency range fH

（3）Plug adjustment, there are 6 shifts in rough adjustment, the difference between shift is 20±1dB, the fine adjustment scale is more than 20dB.

（4）Response asymmetry of positive and negative pulse<1dB

7、Time window

（1）Window width：adjustable，50HZ low 15°～ 150°。

（2）Window location: each window can be circumrotated 0°～ 170°.

（3）Two time windows can be opened separately or together.

（4）There is one-time bombardment, the bombardment time is about 20ms (it is for taking picture)

8、Pulse peak value form

（1）Linearity scale finger meter head 0—100, the error is ±5%（totally）

（2）Logarithm scale finger meter head 0—10—100, the error is ±5%（totally）

（3） Digital meter head: 3.5 digits LED digital display 0—100, the error is ±3%（totally）

9、Test voltage meter

（1）Measuring range 100KV(100KV voltage meter resistance R)

（2）Display: 3.5 digital voltage meter

（3）Error: ±3%

10、Zero mark system

（1）The zero mark of inner zero mark generator can change the polarity, and can circumrotate 0～180°to make the real zero mark location which is made by this voltage and resistance R matches case.

（2）Zero mark is constant with all of the ellipse scan frequency.

11、Structure

（1）Volume: 430×90×480mm3

（2）Weight：about 12KG。

HYG-2005 multi-channel partial discharge detector has high sensitivity, wide application range, large area LCD display, clear test waveform, continuous measurement or single measurement, high-frequency elliptical scanning (the uptake power is less than 1 volt-ampere), large dynamic range of amplification system, multi-band combination (nine kinds), auxiliary zero-scale system, discharge meter digital. Show. The discharge readings can be more accurate and stable in both small and large signals.

HYG-2005 partial discharge instrument is a portable instrument with small volume and light weight. It is a powerful assistant tool for researching and developing new high voltage electrical products and improving product quality. It is also an effective testing instrument for judging whether the equipment is normal or not. The instrument is used in conjunction with JZF-8 or JZF-10 calibration pulse generator. Particularly suitable for the power sector, manufacturers and scientific research institutes and other widely used a practical partial discharge testing instrument.
