Working Principle
High‑voltage test equipment simulates lightning impulse voltages to evaluate the transformer’s insulation withstand capability and verify its high‑voltage protection performance;
Electrical testing instruments precisely collect data and perform computational analysis to measure key electrical parameters such as DC resistance, turns ratio, and dielectric loss, thereby determining the equipment’s operational performance;
Transformer oil analysis equipment utilizes high‑precision sensors and microprocessing systems to analyze the dielectric strength, moisture content, and gas composition of transformer oil, assessing the internal operating condition of the transformer;
All devices work in concert to provide comprehensive multi‑dimensional testing of the transformer’s electrical properties, insulation, oil quality, and high‑voltage withstand capability, accurately identifying potential risks and completing standardized quality assessments.
