160 kVA Three Phase Cast Resin Dry Type Transformer Low Loss Energy Efficient
Progress Test
Manufacturing progress for the 160 kVA three-phase cast resin dry type transformer commences with core material validation, measuring specific core loss via Epstein frame at rated flux density to confirm low-loss silicon steel performance. Winding coils undergo layer-by-layer high-potential testing and resistance mapping for uniform conductivity and insulation integrity. Pre-casting assembly includes precise dimensional checks of conductor placement and spacer alignment using laser gauging. Initial vacuum pressure impregnation trials monitor resin penetration and bubble elimination through X-ray imaging. Early core-coil integration features low-voltage excitation for harmonic and magnetization current profiling. These incremental validations, supported by digital traceability, establish baseline quality and low-loss characteristics essential for energy-efficient operation.

Factory Acceptance Testing for the 160 kVA three-phase cast resin dry type transformer starts with precise turns ratio measurement across all taps using automated bridge equipment, verifying accuracy within 0.2%. No-load loss and excitation current are quantified at 90-110% rated voltage to confirm core efficiency and low magnetizing demand. Winding resistance is recorded at reference temperature for accurate load loss calculation. Routine dielectric tests include applied voltage withstand at specified levels and insulation resistance exceeding 1000 MΩ. Partial discharge measurement under induced overvoltage limits levels below 10pC.
