TCN describes grid collapse as a temporary disturbance
Reacting to the incident, TCN’s General Manager, Public Affairs, Ndidi Mbah, explained that the bus section of a current transformer exploded at 330kV Jebba Transmission Substation, triggering the temporary shutdown.
“The Transmission Company of Nigeria hereby states that the national grid experienced a temporary disturbance at about 8:15 am, today, 19th Oct. 2024.
“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 the outbreak of fire and further damage to adjacent equipment.
“The action of the protection system led to a temporary disturbance on 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,” Mbah said in a statement.
