MSXB-F-270kVA 270kVAC Resonance Test System
This device is primarily designed for AC withstand voltage testing of 35kV and 110kV cables, 110kV main transformers, GIS, and circuit breakers. It has a wide range of applications and is an ideal withstand voltage testing equipment for high-voltage testing departments at the provincial, municipal, and county levels, as well as power installation and maintenance engineering units. The device mainly consists of a variable frequency power supply, excitation transformer, reactor, capacitive voltage divider, and compensation capacitor.

1. It has protection functions such as overvoltage, overcurrent, zero-start, and system detuning (flashover).
2. The weight and volume of the equipment are 1/10-1/30 of ordinary testing devices. The power required for testing is only 1/10 of the test capacity.
3. The device has three operating modes: fully automatic mode, manual mode, and automatic tuning manual voltage boosting mode.
4. Data storage and printing: Stored data is numbered digitally, making it easy for users to identify and retrieve.
5. When the device automatically sweeps the frequency, the starting frequency can be set arbitrarily within the specified range. 6. DSP platform technology: Allows for adding or removing functions and upgrading according to user needs; the human-machine interface is more user-friendly.
7. Improves the output voltage waveform.
8. Prevents large short-circuit currents from damaging the fault point.
9. Prevents any recovery overvoltage.
