Taiyuan, Shanxi – On July 1, 2026, the technical service team of Wuhan Huayi Electric arrived at a client's facility in Taiyuan to conduct comprehensive on-site training for the XZB-44kVA/44kV Frequency-Variable Series Resonance Test System.
The training session, which combined theoretical instruction with hands-on demonstrations, was designed to empower the client's operations and maintenance (O&M) personnel. The goal was to ensure they could independently and safely perform AC withstand voltage testing on critical infrastructure like high-voltage cables and switchgears.
High-Performance Equipment for Precision Testing
The XZB series, independently developed by Huayi Electric, is a flagship solution for the power industry. The delivered system features a 44kVA rated capacity and a 44kV maximum output voltage.
Key Features of the XZB-44kVA/44kV System:
Intuitive Interface: Equipped with a high-definition touchscreen.
Smart Automation: Integrated automatic boosting and intelligent resonance frequency locking.
Safety First: Multiple protection layers for over-voltage and over-current scenarios.
Data Management: Automatic data storage and on-site report printing.
This system is widely applicable for preventative AC Hipot tests on 10kV and 35kV switchgears, cables, and transformers, delivering reliable performance in both indoor distribution rooms and rugged outdoor environments.
Step-by-Step Practical Training
The training began with a standardized setup of the complete test set, including the Frequency-Variable Power Source, Excitation Transformer, High-Voltage Reactors, and Capacitive Voltage Divider.
Using the system's auto-tuning function, the team quickly locked the resonance frequency at 54.6Hz, setting the stage for precise measurements. The practical phase proceeded in stages:
Pre-test: A stabilization check at 12kV.
Rated Test: Stepping up to the target 22.08kV for a continuous 60-minute duration.
Throughout the test, the equipment remained exceptionally stable. Real-time data was displayed on the touchscreen, and final reports were automatically generated and archived, confirming a successful and compliant test result.
Empowering Operators through One-on-One Guidance
Huayi Electric's engineers provided detailed walkthroughs on core operations, including system self-checks, frequency tuning, emergency stop protocols, and data archiving.
Beyond basic operation, the training focused on safety protocols, such as maintaining safe clearances and standardizing wiring sequences. Through one-on-one guidance, every participant gained the confidence to handle the equipment independently, ensuring long-term operational safety for the client's power assets.
Client Recognition & Future Partnership
The client praised the XZB system for its high degree of intelligence and portability, noting that the safety-centric design significantly reduces the risks associated with high-voltage testing. "The on-site training solved our practical operational challenges," a client representative noted. "It gives us great confidence in our partnership with Huayi Electric."
