Product Introduction
The MOEORWS-108kVA/54kV Variable Frequency Series Resonant AC Withstand Voltage Tester is a high-voltage testing device specifically designed for AC withstand voltage testing of 10kV/35kV cables, 10kV switches, and instrument transformers. It consists of a variable frequency control power supply, an excitation transformer, a reactor, and a capacitive voltage divider, and is suitable for use by municipal, county-level high-voltage testing departments and power installation and maintenance engineering units.
Based on the principle of series resonance, this device significantly reduces the test power supply capacity, the size and weight of the equipment , and outputs a pure sine wave. It has multiple protections such as overvoltage, overcurrent, zero-position start, and flashover. It supports three working modes: fully automatic, manual, and automatic tuning with manual voltage boost. It can store and print test data. The DSP platform design facilitates function upgrades and human-machine interaction, taking into account both on-site portability and test safety. It can efficiently complete AC withstand voltage tests on various power equipment.

Product Features and Applications
- The test power supply capacity is only 1/Q of that of a conventional device , and the weight and volume of the equipment are about 1/10 of that of a conventional device .
- Output waveform distortion rate <1.0%, avoiding harmonic breakdown;
- When the test sample breaks down, the circuit quickly becomes detuned, with no large current burn-out and no recovery overvoltage.
- Lightweight and easy to move and connect on site, it is suitable for testing various types of samples.
