Repairs on 132 / 33 kV transformer in Sokoto substation

Nigeria, Sokoto: The Transmission Company of Nigeria, TCN, has completed repair work on one of its 60 MVA 132 / 33 kV power transformers in its Sokoto Transmission Substation, Sokoto State.

In the statement issued by the company, the General Manager, Public Affairs, Mrs. Ndidi Mbah, explained that the repair was carried out by TCN in-house engineers.

The transformer, Mbah explained further, developed fault on 18 March, 2020, due to frequent circulation of 33 kV feeder fault currents within the transformer. The oil filtration will commence on 25 March, 2020.

“Work is also ongoing on one of the 30 MVA 132 / 33 kV power transformers in the substation which was shut down by TCN, to take care of transformer oil degradation and leakage,“ she added.

Consequently, TCN has been unable to supply bulk electricity from the transformers to Kaduna Disco for onward distribution to its customers in and around Sokoto State, who take supply from the faulty transformers in the Sokoto Substation. “As soon as the oil filtration is completed, the 60 MVA power transformer will be energized. Work is on-going to urgently seal the oil leakage problem on the 30 MVA transformer.“

“TCN sincerely regret inconveniences caused to the government and electricity customers in Sokoto State, and pledge to expedite ongoing works on the transformers, to ensure normal bulk supply is restored to the Sokoto Substation,” Mbah added.
