Transformer Potential Transformer (PT) replacement involves removing a faulty or outdated PT and installing a new one to ensure accurate voltage measurement and system protection. PTs are critical for stepping down high voltages to safer levels for metering and monitoring in power systems. Over time, PTs can degrade due to insulation failure, environmental conditions, or electrical stress. Timely replacement ensures continued accuracy in metering, protection relay operation, and overall system reliability. The replacement process includes de-energizing the system, safely removing the old unit, proper installation of the new PT, and thorough testing. Skilled technicians ensure safe, efficient, and compliant replacement.
