Key Stages in SIP's Transformer Testing and Commissioning Process

Pre-Testing Inspection: A thorough visual inspection of the transformer is conducted to identify any physical damage or anomalies before the commencement of testing. Insulation Resistance Measurement: High-voltage DC tests are performed to assess the integrity of the insulation system between windings and between windings and ground. Winding Resistance Measurement: DC resistance measurements are taken to verify the condition of the windings and detect any potential abnormalities. Turns Ratio Measurement: Precise measurements are taken to ensure the accuracy of the voltage transformation ratio. Impedance and Load Loss Measurements: These tests determine the transformer's voltage drop and power losses under load conditions. No-Load Loss Measurement: Measurements are taken to determine the core losses of the transformer when operating without load. Dielectric Withstand Tests: High-voltage AC tests are performed to verify the ability of the insulation system to withstand high voltages without breakdown. Impulse Voltage Tests: High-voltage impulse tests are conducted to simulate lightning strikes and assess the transformer's ability to withstand transient overvoltages. Short-Circuit Tests: These tests are performed to determine the transformer's short-circuit withstand capability and to verify the accuracy of its protective devices. Temperature Rise Tests: Tests are conducted to measure the temperature rise of the transformer under various load conditions to ensure compliance with thermal limits. On-Load Tap Changer Tests: Functional tests are performed on the on-load tap changer to ensure its proper operation and reliability. Commissioning and Handover: Upon successful completion of all tests, the transformer is commissioned and handed over to the client, along with comprehensive test reports and documentation.
