タイトルまたは説明

 PDST series PD testing system for XLPE cable suits the test of PD detect, withstand test and PD fault locate of the XLPE cables under **0kV. The relevant recommendations; GB/T*********2,GB/T********2 and IEC*********5. PD testing system has the advantage of the compact structure, multi-function, easy operate and satery. It can supersede the analogously equpment of foreign production. It is composed of high voltage reactor, double shield isolation transformer, regulator, high voltage capacitive divider, high voltage injection capacitor, PD detector, PD fault locator and shielded room.

2.Main feature
● PD level：≤ 2Pc
● Quality factor：Q≥*0
● Accuracy of fault locating：≤±2.5m(or±1%）
● Accuracy of volatge measurement：≤±3%
● PDST series PD testing systemhas the function of timer, ARC detector,interlock, over current protectoin, zero start and output tap setting control. Turning range can word on the PD test, withstand test and fault locate of power cable of max. cross-section **0MM2, longest length **0m for rated voltage under **0KV.

3.Main feature of shield room and comtrol room
● Resistance of ground is less than 1Ω or less than resistance of ground power distribution.(These shall be done by user accordingto our drawing)
● Resistance of insulating layer ≥***0MΩ
● Attenuation of shield room: *0kHz***0kHz：*0dB**0dB;
**0kHz***0MHz：*0dB***0dB.
● Dimensions of the shield room suits the user's requirement.The whole structure of the building is made of steel frames.The wall is covered with steel plate.Sandwich-structure color steel plates filled with foam are used to decorate the outside wall.The comtrol room is composed of sandwich-structure color steel plates, the window and door is made of aluminum alloy.The floor covered with intemal decoration floor plates.
