FAQ
Q1: What is a high-voltage AC resonant test system?
It is testing equipment that uses series resonance to perform AC withstand voltage tests on compatible electrical equipment. The system is selected according to the test object and the required testing procedure.
Q2: Why is variable frequency control important?
Variable frequency control allows the operating frequency to be adjusted to match the characteristics of the test circuit. Under suitable conditions, resonance helps reduce the reactive power required from the input supply.
Q3: Can testing laboratories use this system for different equipment categories?
Potential applications include compatible power cables, GIS, switchgear, and other high-voltage electrical equipment. Each application requires an assessment of the test object and its testing requirements.
Q4: Is this equipment suitable for on-site electrical testing?
It may be considered for compatible field-testing and commissioning projects. The site layout, operating conditions, test procedure, and equipment requirements should be confirmed before use.
Q5: How can a testing company determine whether the system is suitable?
Identify the target equipment, required AC withstand test, applicable standard or procedure, electrical characteristics, and testing environment. The technical team can then evaluate the suitability of the system configuration.
