According to The Nation, the Transmission Company of Nigeria (TCN) has attributed the recent collapse of the national grid to an explosion in the bus section of a current transformer at the 330kV Jebba Transmission Substation.

The incident activated the protection system, which swiftly curtailed the explosion, preventing a fire outbreak and averting further damage to nearby equipment.

Mrs Ndidi Mbah, the General Manager of Public Affairs at TCN, confirmed the details in an official statement.

She said: “According to the report from the NCC, 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.”

Describing the situation as a temporary disturbance, she said: “The Transmission Company of Nigeria hereby states that the national grid experienced a temporary disturbance at about 8:15am, today, 19th Oct. 2024.”

According to the statement, the action of the protection system led to a temporary disturbance on the grid.

TCN said: “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.”
