MSXB-F-8100kVA 500kV High Voltage Hipot Test Set
This device is primarily designed and manufactured for AC withstand voltage testing of 110kV and 220kV, 1000mm² cables, and for testing 110kV, 220kV and lower voltage circuit breakers, GIS, PTs, CTs, and insulators.
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, and capacitive voltage divider.

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/Q 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: Functions can be added or removed and upgraded according to user needs; the human-machine interface is more user-friendly.
7. Improved output voltage waveform. 8. Prevents large short-circuit currents from burning the fault point.
9. No recovery overvoltage will occur.
