A high voltage test set is an instrument used to test the insulation properties of electrical equipment and devices, such as cables, transformers, and switchgear.

The AC 30 kV, 100 mA high voltage test set you mentioned is designed to generate a high voltage AC output of 30 kV and a maximum output current of 100 mA. This test set typically consists of a high voltage transformer, a voltage regulator, a control unit, and a measuring unit.

During the test, the high voltage output is applied to the equipment being tested, and the test set measures the leakage current and the insulation resistance of the equipment. The results of these measurements are used to evaluate the quality of the insulation and to detect any defects or faults that may be present.

It is important to note that high voltage testing should only be performed by trained and qualified personnel, and all necessary safety precautions should be taken to avoid electrical hazards.

The technical specifications of an AC 30 kV, 100 mA high voltage test set may vary depending on the Requirments of Clients. However, here are some typical specifications you might find:

1. Input power: The input power required to operate the test set may range from 220V to 440V AC.

2. Output voltage: The test set is designed to generate an AC output voltage of 30 kV.

3. Output current: The maximum output current of the test set is 100 mA.

4. Frequency: The frequency of the output voltage is usually between 50 Hz and 60 Hz.

5. Duty cycle: The duty cycle of the test set is typically 30 minutes at full load, followed by 30 minutes of rest.

6. Accuracy: The accuracy of the test set is usually within 1% of the rated output voltage.

7. Overload protection: The test set is equipped with various safety features, such as overload protection, short-circuit protection, and over-temperature protection.

8. Control panel: The control panel of the test set allows the user to adjust the output voltage and current, set the test duration, and monitor the test results.

9. Measuring unit: The test set usually includes a measuring unit that can measure the output voltage, output current, leakage current, and insulation resistance of the equipment being tested.
