Transformer explosion, cause of grid collapse, says TCN

The Transmission Company of Nigeria (TCN) has blamed the collapse of the national grid on the bus section of a current transformer that exploded at 330kV Jebba Transmission substation.

It said the protection system was activated, prompting the busbars to curtail the explosion, thereby preventing outbreak of fire and further damage to adjacent equipment.

Its Public Affairs, General Manager, Mrs Ndidi Mbah disclosed this in a 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.”
