Portable Variable Resonant Withstand Voltage Test Set , For 35KV &10KV Cable Test , 30~300Hz Test Frequency

I. Product Usage :

This test set model FKTF-81KVA/27KV, 54KV is designed for 10KV / 35KV class XLPE cable ,power transformer, CB,CT/PT, busbar in 35KV power substation to perform on-site AC withstand voltage test with variable frequency resonant circuit technology; the highest test voltage is no more than 27KV ,54KV; test frequency: 30-300Hz; the duty cycle is no more than 60mints. it can help customers to perform preventive  test or hand-over test on  AC withstand voltage test 

Test range of the set is as following:transformer

1. 500m of 35kV/300mm2 cable, test frequency 30-300Hz, test voltage 52kV, test time 60min.

2, 2000m of 10kV/300mm2 cable , test frequency 30-300Hz, test voltage 22kV, test time 5min.

3, 10kV/31500kVA main transformer , capacitance ≤ 0.015uF, test frequency 40-300Hz, test voltage 54kV, test time 1min.

4, CB,CT/PT, busbar in 35KV power substation , test frequency 40-300Hz, test voltage does not exceed 95kV, test time 1min.

The whole test set consists of variable frequency power source , excitation transformer , 3pieces of reactors, and high voltage measurement devider(capacitive voltage divider). This type of test set is most suitable for 35KV power sub-station
