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.
