Power supply in Mymensingh district was disrupted for nearly eight hours after a fire broke out at a sub-station of Kewatkhali Power Grid yesterday morning.
The fire started around 10am from a circuit breaker and spread to the nearby control room, said Rafiqul Islam, chief engineer of Power Development Board in Mymensingh.
Two fire-fighting units brought the blaze under control soon, he said, adding that power supply to the entire Mymensingh division was halted following the incident.
However, power supply to Jamalpur, Sherpur and Netrakona districts was restored around 11:30am. "We have replaced the burnt circuit breaker with a new one," the chief engineer said.
Md Masudul Haque, executive engineer of Power Grid Company, said the power supply was restored in Mymensingh district around 7:30pm.
The incident happened two days after a fire broke out at the main station of Kewatkhali Power Grid, leaving the entire division out of electricity for several hours. Restoration work of power lines damaged during Tuesday's incident was going on when yesterday's fire broke out.
A four-member probe committee was formed by the district administration to look into Tuesday's incident.
