Device Features
1. Large output capacity, high output voltage, and combinable reactors for AC withstand voltage tests on different test objects.
2. Compact size, light weight, especially convenient for field tests.
3. Good protection functions, including overvoltage protection, overcurrent protection, time protection, flashover protection, overheating protection, and module protection.
4. Extremely simple operation, with both manual and automatic modes.
5. Large screen for clear test data display, and test results can be printed.
6. No overvoltage risk after test object breakdown, minimizing damage to the test object.
7. Low power supply capacity required for tests, only a fraction of that needed for power frequency transformer tests, solving the problem of difficult power supply on site.
