The HZG1101 Variable Frequency Series Resonance Test System is designed for AC withstand voltage testing of power cables, transformers, GIS, switchgear, generators, busbars and other high-voltage electrical equipment.
The system uses variable-frequency series resonance technology to generate high AC test voltage with relatively low input power. By adjusting the resonance frequency according to the capacitance of the test object, it provides stable and efficient AC withstand testing. The system consists of a variable-frequency power supply, excitation transformer, high-voltage reactor and capacitive voltage divider, with reactor quantity, test voltage and system capacity configurable to the test object.

FAQ
What can the HZG1101 test?
It can be configured for AC withstand testing of power cables, transformers, GIS, switchgear, generators, busbars and other high-voltage equipment.
Can it automatically find the resonance point?
Yes. The system can automatically scan the selected frequency range and locate the resonance point.
How is the reactor configuration selected?
It depends mainly on the required test voltage, test object capacitance and operating frequency. For power cables, cable length is also an important factor.
What information is needed for a quotation?
The test object, required test voltage, cable length/capacitance, testing standard and test location.
