Product Description

Product Description

The SXBP Series Variable Frequency Resonant Test System is developed for high-voltage AC insulation testing where reliable test voltage generation, load adaptability and flexible equipment configuration are essential.
Designed around variable-frequency resonance technology, the system combines a frequency conversion power supply, excitation transformer, resonant reactors and a control and measurement unit. The configuration can be selected according to the electrical characteristics of the test object and the required test conditions.


Typical system components

Variable Frequency Power Supply

Excitation Transformer

Resonant Reactors

Control and Measurement Unit


Key Advantages

Configuration Based on Actual Load
The system selection process considers the electrical characteristics of the test object rather than the voltage rating alone. This supports more appropriate equipment matching for different applications.

Modular System Arrangement
The use of separate functional components provides flexibility when configuring the equipment for different test voltage and load requirements.

Adjustable-Frequency Testing
Variable-frequency operation supports resonance matching within the specified operating range, helping accommodate different capacitive loads.

Practical Equipment Handling
The catalogue describes a lightweight component design, with certain components weighing approximately 50 kg or less. Actual weight and handling requirements vary by model and component rating.

Application-Specific Technical Evaluation
The final configuration can be assessed against project requirements, including the required test voltage, capacitance, test duration and applicable standards.


Applications

Power Cable Insulation Testing

GIS and Switchgear Testing

Transformer Testing

Other Electrical Apparatus


FAQ

1. How is the resonant reactor configuration determined?

The resonant reactor configuration depends on the required test voltage, test-object capacitance, operating frequency and system rating. The manufacturer evaluates these parameters to determine a suitable reactor arrangement for the intended application.​

2. Does the maximum output voltage determine the system's testing capacity?

No. Maximum output voltage is only one factor in system selection. Rated capacity, output current, test-object capacitance, operating frequency and test duration must also be considered. The complete configuration should be evaluated against the actual test requirements.
