The Transmission Company of Nigeria (TCN) has announced a fresh power outage in parts of Abuja following the tripping of a 100MVA power transformer at the Apo 132kV/33kV Transmission Substation.

TCN disclosed this in a notice issued on Wednesday, explaining that the outage was caused by oil spillage on the red-phase high-voltage (HV) bushing of the transformer.

According to the company, the incident resulted in the tripping of four 33kV feeders, namely H31, H33, H35 and H37, thereby disrupting electricity supply to several parts of the Federal Capital Territory.

“TCN hereby informs the public that the 100MVA TR4 transformer at the 132/33kV Apo Transmission Substation tripped in the early hours of today.

“Our maintenance crew are already carrying out a detailed investigation on the transformer to ascertain the exact cause of the tripping, to enable us effect repairs and restore the transformer,” TCN stated.

Following the incident, the Abuja Electricity Distribution Company (AEDC) confirmed a power outage affecting areas including Apo Legislative Quarters, Lokogoma, Apo Resettlement and other parts of Abuja.

The latest incident comes shortly after TCN announced a blackout in parts of the Federal Capital Territory due to scheduled maintenance activities.
