75 kVA Transformer Testing

At EverNew, every 75 kVA transformer undergoes a comprehensive series of routine tests before leaving the factory, strictly adhering to ANSI/IEEE C57.12.90、ANSI/IEEE C57.12.00 、IEC 60068standards. These tests are crucial for guaranteeing the performance and safety of the transformers. The routine tests include:

1. Ratio Test: Ensures the correct voltage ratio of primary to secondary windings.Ratio accuracy within ±0.5%.

2. Polarity Verification: Confirms the correct polarity of the transformer windings.Correct polarity configuration confirmed.

3. No-Load Loss Evaluation: Measures the power losses when the transformer is energized but not supplying any load.No-load losses corrected to 85°C, typically < 1% of rated power.

4. Excitation Current Measurement: Assesses the current required to energize the transformer at no load. Excitation current at 105% rated voltage, typically < 1% of rated current.

5. Load Loss and Impedance Measurement: Measures the power losses and impedance under full load conditions. Load losses corrected to 85°C, typically < 2% of rated power. Impedance within specified range, usually 2-5%.

6. Applied Voltage Test: Verifies the insulation integrity by applying a high voltage to the windings.Applied voltage typically 2-3 times the rated voltage for 1 minute without breakdown.

7. Induced Voltage Evaluation: Tests the transformer’s ability to withstand higher than normal operating voltages. Induced voltage typically 1.5 times the rated voltage for 60 seconds without breakdown.

8. Transformer Tank Leak Test: Ensures the tank is free from leaks.No detectable leaks under test conditions.

9. Prueba de aumento de temperatura: Measures the temperature rise under full load conditions.Temperature rise typically < 65°C over ambient temperature.

10. Prueba de resistencia de aislamiento: Measures the resistance of the insulation system.Insulation resistance typically > 1,000 megaohms.

11. Prueba de descargas parciales: Detects partial discharges to ensure insulation integrity.Partial discharge levels typically < 10 pC.

12. Sound Level Test: Measures the sound levels emitted by the transformer. Sound levels typically < 60 dB(A) at 1 meter distance.

13. Short-Circuit Withstand Test: Verifies the transformer’s ability to withstand short-circuit conditions.Transformer remains intact and operational after test.

14. Impulse Test: Simulates lightning strikes and high-voltage surges.No insulation breakdown under impulse conditions, typically 5-10 times the rated voltage.

15. Humidity and Environmental Tests: Exposes the transformer to various humidity and environmental conditions. No degradation in performance under test conditions.

16. Mechanical Strength Test: Assesses the mechanical strength of the transformer’s components. Components withstand specified mechanical stresses without damage.

By implementing these rigorous testing procedures, EverNew ensures that each 75 kVA transformer meets the highest standards of quality and safety, providing reliable performance for our customers. If you need more information or advice on your transformer project, please feel free to contact us.
