Product Description
SXBP 2000KVA/500kV Variable Frequency AC Resonant Test System
A Variable Frequency AC Resonant Test System is designed for AC withstand voltage testing of compatible high-voltage electrical equipment. It works on the series resonance principle, adjusting the operating frequency to match the electrical characteristics of the test circuit. This testing method is particularly relevant to capacitive test objects that require high-voltage AC insulation testing.
For power cable manufacturers, cable testing laboratories, electrical contractors, and power transmission projects, an AC resonant test system can be evaluated for cable insulation testing and high-voltage acceptance testing. The suitable configuration depends on cable characteristics, the required test procedure, and site conditions.

FAQ
Q1: What is a Variable Frequency AC Resonant Test System?
It is high-voltage test equipment that uses the series resonance principle to perform AC withstand voltage tests on suitable electrical equipment. The system adjusts the operating frequency to achieve resonance with the test circuit.
Q2: Why use series resonance for power cable testing?
Power cables can present a capacitive load during AC testing. Under suitable resonance conditions, the system can reduce the reactive power required from the input supply compared with directly supplying the full reactive load.
Q3: What is AC withstand voltage testing used for?
AC withstand voltage testing evaluates the insulation performance of electrical equipment under specified test conditions. The test method and acceptance criteria should follow the applicable standard or project requirements.
Q4: Can this system be used for cable factory and field testing?
Potential use depends on the cable type, test procedure, electrical characteristics, and site conditions. These details should be confirmed before determining whether the system is suitable for a particular factory or field-testing project.
Q5: How do I choose an AC resonant test system for power cables?
Provide the cable type, test requirements, cable configuration, required test voltage, test duration, and site conditions. This information helps the technical team assess system suitability and the required configuration.
