Product Description
The Variable Frequency Series Resonant Test System is an advanced high voltage testing solution designed for AC withstand voltage tests of large-capacity electrical equipment, including power transformers, GIS, XLPE cables, busbars, circuit breakers and other high voltage insulation systems.
Sansion Power SXBP Series Variable Frequency Series Resonant Test System adopts the principle of LC series resonance technology, which generates high voltage output with lower power requirements compared with traditional AC test transformers.
The system is widely used in power utilities, transformer manufacturers, electrical testing laboratories and high voltage maintenance departments for commissioning tests, preventive maintenance tests and insulation performance verification.
The complete system mainly consists of:
- Variable frequency power supply
- Excitation transformer
- High voltage reactor
- Capacitive voltage divider
- Compensation capacitor (optional)
The modular design makes transportation and field installation easier, especially for large-capacity high voltage equipment testing.

Customer FAQ
Q1: What equipment can be tested by this series resonance system?
A: It can test transformers, GIS, cables, reactors, generators, switchgear, busbars and other capacitive high voltage equipment.
Q2: Why use a series resonance test system instead of a traditional AC hipot tester?
A: Because the series resonance system requires much lower power capacity while achieving high voltage output, making it smaller, lighter and more suitable for field testing.
Q3: Can it be customized according to different voltage levels?
A: Yes. The system can be customized according to customer requirements, including test voltage, capacity, frequency range and tested equipment.
