Quality Control & Testing
- Routine Dielectric Tests
Verifies impulse and power-frequency withstand voltages to confirm 167 kVA insulation reliability.
- No-Load Loss Measurement
Benchmarks core losses against IEEE C57.12.20 standards to verify specified operational efficiency limits.
- Load Loss Verification
Measures copper/aluminum winding losses at rated 167 kVA current to evaluate thermal performance.
- 100% Helium Leak Detection
Pressurizes every pole-mounted tank to validate tank hermetic sealing against fluid leakage.
- Induced Potential Testing
Doubles operating voltage to validate interlaminar insulation strength under grid voltage spikes.
- Winding Resistance Calibration
Measures precision milliohm values to ensure balanced electrical performance and minimize hot spots.
