Partial Discharge Test System

Partial Discharge Test System
Product name:Partial Discharge Test System

I Description:

This system is special for measuring partial discharge of transformer, motor, instrument transformer, cable, GIS, switch and arrester, etc.

This system has special dual-channel measuring function which allows to measure several test articles or several points on same article. So it is suitable for diagnosing discharging positions of big size transformer.

II Buildup

1)      Non-partial-discharge test transformer

2)      Non-partial-discharge regulator & control panel

3)      Isolation filter

4)      Coupling capacitor

5)      Partial discharge test meter

6)      Current-limiting resistance, cables, etc.

III Main features

l  Full program-control working method, very convenient measuring and analyzing.

l  Word prompting to operate, simple operation

l  Partial discharge figure and data can be saved and printed out, automatically generating test report

l  Freely choose ellipse or beeline displaying method, can statically measure, observe and analysis partial discharge impulse of one cycle test voltage.

l  Newest 2D and 3D atlas displaying, more information, easier to distinguish discharge impulse and disturbance impulse.

l  Special color columns and digital indicating discharging impulse peak value.

l  Special numerical windowing technique, avoiding effect to test by disturbance.

l  Dual-channel measuring and digital differential technique can build up impulse polarity distinguishing circuit or balance measuring circuit, effectively restrain signal of disturbance impulse.

l  Convenient for establishing measuring & positioning data

IV Technical parameters

l  Test channels: dual-channel

l  Test sensitivity: 0.1Pc

l  Test frequency band: 3dB band width, 10kHz~300kHz

l  Dynamic range of gain: 120dB

l  Low-side of filter: 10, 20, 40KHz

l  High-side of filter: 100, 200, 300kHz

l  Synchronization frequency: 50, 100, 150, 200 or any
