Transformer Rewinding is the process of replacing the electrical coils, or windings, inside a transformer. This is a cost-effective and sustainable alternative to purchasing a new unit when a transformer's performance has degraded due to factors like heat, age, or electrical stress. The process involves a thorough inspection and dismantling of the transformer, followed by the careful removal of the old windings. New copper or aluminum windings are then meticulously installed to precise specifications, and the transformer is reassembled and rigorously tested to ensure it meets safety and performance standards. This can significantly extend the life of the unit and improve its efficiency.
