The replacement of LT (Low Tension) and HT (High Tension) bushings in a transformer is a critical maintenance task that ensures safe and efficient power transmission. Bushings are used to provide a safe electrical interface between the transformer and external conductors. Over time, bushings can wear out due to aging, moisture, or electrical stress, leading to insulation failure or leaks. Replacing damaged or deteriorated bushings involves carefully removing the old components, inspecting the transformer for any damage, and installing new, high-quality bushings that meet the required voltage and current specifications. Regular bushing replacement helps prevent transformer failures and ensures reliable operation.
