Wuhan, China – In August 2026, Wuhan Huayi Power Technology Co., Ltd. (Wuhan Huayi) completed the delivery of a customized XZB-108kVA/108kV Frequency Series Resonance Test System to a leading metrology and testing institute in Henan province.
This project reinforces Wuhan Huayi's reputation as a premier provider of high-precision electrical diagnostic tools for national-level testing and calibration laboratories.
Meeting the Gold Standard of Metrology
Professional metrology institutes demand the highest levels of accuracy, stability, and regulatory compliance. Since July 2026, our technical team has worked closely with the client to align our equipment with their rigorous daily testing workflows and international standards (IEC/IEEE equivalent).
Through one-on-one technical consultations, Wuhan Huayi addressed complex requirements regarding data traceability, equipment adaptation for various field conditions, and operational safety. This collaborative engineering approach ensured the final solution was perfectly "fit-for-purpose."
The Solution: XZB-108kVA/108kV Series Resonance System
The core of this delivery is the XZB-108kVA/108kV Frequency Conversion Resonant Test Set. This system is specifically engineered for performing AC Withstand (Hipot) Tests on critical infrastructure, including:
Power Cables: High-capacitance XLPE cables.
Main Transformers: Ensuring insulation integrity under stress.
GIS and Switchgear: Testing in confined, high-voltage environments.
The system features industry-leading frequency conversion technology, delivering stable waveforms and ultra-precise measurement data that meet the stringent audit requirements of professional calibration bodies.
Rigorous Quality Assurance and On-Time Delivery
Following the contract signing on August 11, our manufacturing facility fast-tracked the production under our ISO-certified quality management system. Each component-including the Variable Frequency Power Supply, Excitation Transformer, and Resonant Reactors-underwent multi-stage quality checks:
Precision Calibration: Verified against high-precision master meters.
Stress Testing: High-load aging and stability verification.
HSE Compliance: Final safety and insulation checks before packaging.
The full system was successfully dispatched on August 18, 2026, meeting the client's urgent project timeline.
Commitment to Global Power Safety
"This successful partnership with a professional metrology unit is a testament to the accuracy of our resonant technology," stated the project manager at Wuhan Huayi. "We don't just sell equipment; we deliver the data confidence that engineers rely on to keep the grid safe."
Wuhan Huayi continues to innovate in the field of HV Diagnostics, providing one-stop technical solutions, operational training, and 24/7 support for utilities, renewable energy farms, and industrial plants worldwide.
