LAHORE: A spokesman for the National Transmission and Despatch Company Ltd (NTDC) has said that NTDC engineers and staff replaced and energised two damaged current transformers (CTs) of 500kV grid station Rewat overnight and restored power supply to IESCO early in the morning (at 05:00) of June 5. The current transformers exploded due to ongoing heatwave in the country. The spokesman said that NTDC team remained busy throughout the night in replacement of transformers. The affected 132kV grid stations were provided power supply through load management and from alternative sources, however, with the replacement of current transformers, the power supply to 132kV circuits of Chakwal and other nearby areas of Rawalpindi was despatched through NTDC network.
