ACB (Air Circuit Breaker) PT (Potential Transformer) replacement is a critical process to ensure accurate voltage measurement and system protection in electrical networks. Over time, PTs can deteriorate due to age, electrical stress, or environmental conditions, leading to inaccurate readings or failures. Replacing a faulty PT restores proper monitoring and enhances the reliability of the ACB system. The replacement involves safely disconnecting the existing PT, installing a compatible new unit, and conducting thorough testing to verify accuracy and performance. Carried out by trained professionals, PT replacement ensures compliance with safety standards, supports precise relay operation, and maintains uninterrupted, efficient power distribution.
