Replacement of LT (Low Tension) and HT (High Tension) bushings in a transformer is a critical maintenance procedure to ensure safe and efficient electrical performance. Bushings provide insulated pathways for electrical conductors passing through the transformer tank. Over time, they may degrade due to electrical stress, environmental conditions, or mechanical damage, leading to oil leaks or insulation failure. Replacement involves safely de-energizing the transformer, draining oil if necessary, removing the faulty bushings, and installing new ones that match the specifications. Proper alignment, sealing, and torque application are essential. Timely replacement prevents faults, enhances safety, and prolongs the life of the transformer.
