The HZG1101 Complete Set of Variable Frequency Series Resonance Test Equipment is designed for AC withstand voltage testing of high-voltage electrical equipment, including 10kV, 35kV, 110kV and 220kV power equipment, substations, transmission lines, transformers, generators and high-voltage cables.
The system adopts advanced variable frequency series resonance technology, using resonance between the high voltage reactor and the capacitive load to generate high voltage and high current. Compared with traditional power frequency withstand voltage test systems, it greatly reduces the required power capacity, equipment size and weight while improving waveform quality and testing safety.
The complete system consists of:
With intelligent frequency scanning, automatic tuning, multiple protection functions and modular design, this equipment is widely used in power utilities, high-voltage testing laboratories, electrical installation companies and maintenance engineering units.

The series resonance principle reduces the required input power to approximately 1/Q of the test capacity, making the system suitable for field environments with limited power supply.
The modular structure eliminates bulky traditional high-power transformers. Single unit weight is ≤65kg, improving portability.
When insulation breakdown occurs, the system automatically loses resonance and reduces current, preventing large short-circuit current damage.
The resonance circuit filters harmonic components and provides a near-sine wave output with distortion below 1%.
It is suitable for AC withstand voltage testing of transformers, cables, GIS, generators, switchgear, substations and transmission lines.
It provides high voltage output with lower input power, better waveform quality and safer fault current limitation compared with traditional testing methods.
Yes. The modular structure is designed for on-site testing applications in substations and power construction environments.
Yes. The system supports automatic frequency scanning, resonance point identification and curve display.
The equipment comes with a 2-year warranty including technical support, troubleshooting assistance and replacement of manufacturing-defect components.
We provide a two-year warranty for the complete variable frequency series resonance test equipment.
