Product Introduction
The HMCXZ-270kVA/270kV AC Variable Frequency Resonant Test System is designed for the design and manufacturing of 66kV and 220kV cables. Its split-core reactor design not only meets the testing requirements for high-voltage, low-current equipment but also satisfies user needs for low-voltage AC withstand voltage tests on 10kV cables and similar applications.
Technical parameter of the whole test system
1)Rated voltage : AC withstand voltage test for 110kV power transformer, CT/PT, insulator, busbar, GIS,etc.
2). Output voltage waveform distortion rate: < 1.0%
3). Continuous working allowed: 30mins under voltage; 60mins if cables testing;
4).The device itself quality factor: Q > 50
5).Cable full load factors: Q > 30 (load related)
6). Input voltage: single phase 220V three phase380V
7). Frequency adjustment range: 30Hz ~300Hz
8). System measuring precision: 1.5%
9). Device with over-voltage,over-current, zero start up ect,protection function
