Transformers are vital components in electrical systems, ensuring efficient power distribution. Before putting a transformer into service, pre-commissioning checks are crucial to guarantee its proper functioning and safety. Here’s a comprehensive guide to the essential pre-commissioning checks for transformers:
- Visual Inspection: Examine the transformer for any physical damage, leaks, or loose connections. Visual inspections help identify potential issues that might affect performance.
- Oil Sample Testing: Collect and test oil samples to assess its condition and detect any contaminants. This test provides insights into the transformer’s insulation and helps prevent potential failures.
- Core Insulation Tests: Conduct tests to ensure the integrity of the transformer’s core insulation. This step is crucial for preventing core-related failures.
- Operational Checks on Protection System: Verify the functionality of the protection system to safeguard the transformer against faults and overloads. Operational checks ensure the transformer operates within safe limits.
- Insulation Resistance Measurement: Measure insulation resistance to assess the overall insulation condition. Low insulation resistance can indicate potential insulation degradation or moisture ingress .
- Electrical Tests: Perform electrical tests, including turns ratio, winding resistance, and impedance tests, to validate the transformer’s electrical parameters and efficiency.
- Instrument Checks: Verify the calibration and functionality of instruments used for monitoring and controlling the transformer. Accurate instrumentation ensures reliable operation.
