Product Description
The SXBP Variable Frequency Series Resonance Test System is engineered for high-voltage AC withstand testing of large-capacity electrical equipment and capacitive loads. Based on variable-frequency series resonance technology, the system combines a variable-frequency power supply, excitation transformer, resonant reactor and related compensation components to establish a controlled resonant circuit. By adjusting the operating frequency, the system can adapt to different test loads and generate the required high AC voltage.

FAQ
1.Can the SXBP system test 220 kV cables? Yes. The system can be configured for 220 kV power cable AC withstand testing. Cable length, capacitance, required test voltage and test duration should be provided for accurate configuration.
2.Can it be used for 500 kV cable testing? Yes. The SXBP series can be engineered for 500 kV cable testing and other EHV applications within the required technical range.
3.What is the output frequency? The output frequency range is 20–300 Hz.
4.Why is the frequency adjustable? Because different test objects have different capacitance values. Variable-frequency operation allows the system to adjust the resonant condition according to the electrical characteristics of the load.
