It functions as an “Efficiency Engine” for power equipment testing. driven by intelligent software, it performs full-sequence automatic testing and data calculation for 10kV-35kV transformers. This reduces on-site workload and testing time significantly while ensuring higher precision than manual desktops.
The system features a Compact, Integrated Structure that combines high-grade insulation materials with advanced measurement hardware. From the Capacitor Cabinet to the Primary Wiring Configuration, every ensuring withstands rigorous high-voltage testing cycles.
It offers dual-layer protection. For the grid, it detects early insulation defects to prevent outages. For the test site, it features Emergency Stop, Over-Voltage Protection, and Automatic Discharge mechanisms to protect both personnel and the expensive equipment under test.
It features “One-Time Wiring” capability. Once connected, the intelligent system automatically switches between test modes (like DC resistance, ratio, and load loss) without requiring manual lead reconnections, streamlining the workflow significantly.
