Isolator Panel PT (Potential Transformer) replacement is a critical maintenance task to ensure accurate voltage monitoring and protection in electrical systems. PTs are used to step down high voltage for measurement and control, and over time, they may degrade due to electrical stress, insulation failure, or aging. Replacing a faulty PT involves safely disconnecting the panel, removing the damaged transformer, and installing a new, compatible unit. Skilled technicians carry out testing and calibration to ensure proper operation. Timely PT replacement enhances system accuracy, safety, and reliability, preventing potential faults and ensuring smooth functioning of the isolator panel.
