    Provides system control, frequency adjustment, voltage monitoring and test operation management.

FAQ

1. What is a Variable Frequency Series Resonance Test System?

A Variable Frequency Series Resonance Test System is high-voltage AC test equipment that uses series resonance technology to generate stable high AC voltage for dielectric withstand testing. It is widely used for testing power cables, transformers, GIS, switchgear, CTs, PTs and other high-voltage electrical equipment.

2. What equipment can be tested with this system?

The system can be used for AC withstand testing of various electrical equipment, including:
• Power cables
• Power transformers
• GIS
• Circuit breakers
• Switchgear
• Current transformers (CT)
• Voltage transformers (VT/PT)
• Insulators
• Other high-voltage electrical equipment
The actual system configuration depends on the voltage and capacitance of the test object.

3. What is the maximum output voltage?

The system can be configured with an output voltage of up to 800 kV RMS, depending on the specific system configuration and testing requirements.
The required test voltage should be confirmed according to the test object and applicable testing standard.

4. What is the output frequency range?

The standard frequency range shown for the system is 20–300 Hz.
Variable-frequency operation allows the system to adjust the resonance point according to the characteristics of different test objects.

5. Why does the system use variable-frequency technology?

Different test objects have different capacitance values. Variable-frequency technology allows the operator to adjust the operating frequency to establish the appropriate resonance condition.
This makes the system more flexible for testing cables, transformers, GIS and other capacitive loads.
