Certificate Verification:

Verify the 500 KVA Transformer’s certification. If the certificate is older than two months, retest the insulation resistance to ensure it meets the required standards.

Insulation Testing:

For the 500 KVA Oil-filled Transformer, use a megohmmeter to test the insulation resistance and confirm the insulation’s integrity. Additionally, perform a Dielectric Absorption Ratio (DAR) test to evaluate the overall condition of the 500 KVA Transformer’s insulation.

Oil Level and Quality:

Check the oil level in the 500 KVA Transformer and ensure that the ventilation holes are unobstructed. There should be no signs of oil leakage. Sample the transformer oil and analyze its dielectric strength, moisture content, acidity, and perform a dissolved gas analysis (DGA) to detect potential issues such as overheating or arcing in the 500 KVA Transformer.

Insulation and Connections:

Inspect both high and low voltage bushings and associated wires in the 500 KVA Transformer for any signs of damage. Ensure that all screws and connections are tight and secure to prevent electrical faults. Use infrared thermography to detect hotspots at connection points, which may indicate loose connections or corrosion in the 500 KVA Transformer.

Tap Changers and Fuses:

Confirm that the tap changer in the 500 KVA Transformer is correctly set according to operational requirements. Inspect and clean the tap changer contacts and mechanism. Perform electrical tests to ensure the proper operation of the tap changer in the 500 KVA Transformer.

Lightning Protection and Grounding:

Inspect the lightning arrester for any signs of damage in the 500 KVA Transformer. Measure the grounding resistance to ensure it meets safety standards, and verify the integrity of the grounding connections and electrodes.

Cooling System:

Inspect the radiators and cooling fans of the 500 KVA Transformer to ensure they are clean and functioning properly. If the 500 KVA Transformer is equipped with an oil circulation pump, check its operation to ensure effective cooling.

Noise and Vibration:

Monitor the 500 KVA Transformer for any abnormal noise or vibration. Such signs may indicate internal problems that require immediate attention to ensure the safe operation of the transformer.
