The Transmission Company of Nigeria (TCN) says the national grid collapsed on Saturday due to an explosion at the bus section of a current transformer at the 330-kilovolt (kV) Jebba transmission substation, Niger state.
In a statement by Ndidi Mbah, general manager (GM), public affairs, TCN said following the incident, the commission activated a protection system, which promptly opened the busbars to curtail the explosion.
“The Transmission Company of Nigeria hereby states that the national grid experienced a temporary disturbance at about 8:15am, today, 19th Oct. 2024,” TCN 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.
“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.”
The system failure earlier today was the third time in a week and the eighth time in 2024.
