General Information

The SXBP Variable Frequency Series Resonance Test System uses variable-frequency series resonance technology to generate stable high AC voltage for insulation and withstand testing. By adjusting the operating frequency to match the characteristics of the test load, the system provides an efficient and flexible solution for high-voltage electrical equipment testing.

The system is designed for 10 kV, 35 kV, 110 kV and other power equipment rated up to 110 kV, with different system configurations available according to the required test voltage and load.

Typical Configuration

Variable Frequency Power Supply
Controls the excitation frequency and provides adjustable output for resonance operation.
Excitation Transformer
Provides voltage conversion between the variable-frequency power supply and the resonant circuit.
Resonant Reactor
Works with the capacitive load to establish the required series resonance condition.
Capacitive Voltage Divider
Provides high-voltage measurement and monitoring during testing.
Control & Protection System
Controls the test process and monitors key operating parameters for safer and more stable operation.

FAQ

Q:What is the main purpose of the SXBP system?

It is used to generate high AC test voltage for dielectric withstand testing of power cables, transformers, GIS, switchgear, CTs, PTs, insulators and other high-voltage equipment.

Q:What is the maximum voltage of the system?

The system can be configured for up to 800 kV RMS, depending on the selected system configuration.

Q:What frequency range does the system support?

The output frequency range is 20–300 Hz.

Q:Why is the test frequency adjustable?

Different test objects have different capacitance values. Variable-frequency operation allows the system to adjust the resonance point to match different loads.

Q:Can it test long power cables?

Yes. It is suitable for AC withstand testing of medium- and high-voltage power cables. For long cables, the cable length and capacitance are important parameters for system selection.
