This series of devices are designed for AC to withstand voltage test of substation primary equipment under 550KV or below, mainly composed of variable-frequency power supply, exciting transformer, reactor, and capacitive Voltage divider.

Features

1. Easy to operate, two working modes: manual and automatic.

2. Can set Test Voltage, frequency range, protective current, and operating time.

3. Smaller size, lighter weight compared with same voltage level same capacity reactor.

4. Small temperature rise at rated load. Strong protection, good stability. Multiple functions are cost-effective.

5. Dry-type epoxy cast, high mechanical strength, good insulation, nice and reliable.

6. Adjustable capacity of a frequency control source.

7. With 220V or 380V single-phase power, convenient for on-site power sourcing.

8. Flexible configuration. Different type reactors for options to meet different test object requirements.
