AC High Voltage Test System
The maximum voltage class is 1800 kV, the maximum capacity is 9 MVA, and the maximum rated current is 30 A.
The AC high-voltage test system is specially designed for testing medium-capacity test specimens in the factory. It is particularly suitable for test scenarios where the load changes during testing (such as pollution, wet, and salt fog tests) or where inductive loads are involved (such as electromagnetic voltage transformers), while maintaining stable test voltage. By stacking and connecting multiple transformers in series, it can achieve ultra-high voltage output while maintaining a reasonable footprint.
Advantage
✅Compact dimensions resulting in minimum space requirements
