July 2025 - Wuhan Goldhome Hipot Electrical Co., Ltd recently completed comprehensive power transformer testing for an overseas power utility company, demonstrating our expertise in high-voltage testing solutions.
Key Testing Services Performed:
Winding Resistance Tests
Our team conducted precise DC resistance measurements to assess winding integrity and contact conditions, following the latest DL/T 596-2021 standards.
Turns Ratio Verification
Using advanced testing equipment, we verified voltage transformation ratios with accuracy up to 0.04% deviation, ensuring proper magnetic balance.
Insulation Diagnostics
Performed dielectric loss angle (tanδ) and capacitance measurements to evaluate insulation quality, with special attention to moisture content and agingL.
Induced Voltage Withstand Test
Executed 100Hz-400Hz frequency sweep tests to examine inter-turn and phase-to-phase insulation without overexciting the core.
Partial Discharge Measurement
Conducted in our shielded laboratory with background noise <2pC, crucial for assessing insulation system integrity8DOC.
