The Transmission Company of Nigeria (TCN) has announced another grid disturbance, less than 96 hours after the first disturbance was reported. This makes it the eighth this year.
The latest one occurred about 8:15am Saturday, October 19.
In a statement, General Manager (GM), Public Affairs of TCN, Ndidi Mbah, said that the bus section of a current transformer exploded at 330kV Jebba Transmission Substation and as expected, the protection system was activated, and this promptly opened the busbars to curtail the explosion, thereby preventing outbreak of fire and further damage to adjacent equipment.
According to her, the action of the protection system led to a temporary disturbance on the grid, assuring that TCN engineers have successfully reconfigured the bursbar arrangements and restored power supply to the station and other parts of the grid.
“Our engineers at Jebba have successfully carried out switchings, isolating the faulty current transformer. They have equally reconfigured the busbar arrangement, restoring power supply to the station and other parts of the grid,” the GM said.
Fours days ago, TCN reported a partial grid disturbance so making it the seventh in the year.
The disturbance affected power supply in the South Southern part of the country such as Eket, Ekim, Uyo, and Itu
Mbah said that the company was making efforts to fully recover the grid.
Mbah said that the slight setback notwithstanding, TCN continued with the grid recovery process, which has reached an advanced stage, ensuring bulk power availability to about 90 per cent of its substations nationwide. Supply, she said, has been restored to the Abuja axis and other major distribution load centres nationwide.
