Introduction:Routine inspections are essential to ensure the safe and reliable operation of transformers under various weather conditions. Here are some simple yet crucial inspections to perform in different weather scenarios:
Windy Weather:During windy weather, it's important to check for any debris that could be easily blown into the transformer area. This debris might pose a risk of falling onto live components. Also, keep an eye on the movement of connecting wires to ensure everything is secure.
Foggy Weather:In foggy conditions, inspect the transformer for any signs of arcing or discharge in the bushings. These conditions can affect the insulation performance and lead to failures.
Snowy Weather:After heavy snowfall, examine the transformer for snow accumulation or ice buildup between the cover and bushings. Ensure that snow does not cover instruments such as oil level gauges, temperature indicators, or gas relays.
After Thunderstorms:Following thunderstorms, check the lightning arresters on all sides of the transformer for any indication of operation. Additionally, inspect the transformer for any damage, cracks, or discharge marks on the bushings.
Sudden Temperature Changes:During abrupt temperature changes, monitor the oil level and temperature closely. Rapid temperature fluctuations can affect the operation of the transformer, requiring adjustments for safe operation.
Performing these routine inspections in different weather conditions ensures the transformer's reliability and minimizes the risk of failures. Regular maintenance helps safeguard equipment and ensures continuous power supply.
