TCN to reduce electrical load shedding, configured to replace old circuit breakers

By on November 21, 2021 0

The Transmission Company of Nigeria (TCN), in its offer to reduce electrical load shedding, has started the rehabilitation and replacement of over 20 year old circuit breakers in the country’s transmission network.

The project, TCN explained, aimed to further improve the bulk transmission of power to distribution centers nationwide.

The rehabilitation and replacement work that was officially announced at the 37-year-old Ajaokuta 330/132 kV substation in Kogi State was in line with TCN’s efforts to ensure that all circuit breakers in its network are certified and operate optimally.

TCN Director General, Public Affairs, Ndidi Mbah, who confirmed this in a statement on Sunday, said the decision to start with Ajaokuta substation circuit breakers was due to the strategic role the substation plays. in the transmission of bulk electricity to the distribution centers of the Abuja Electricity Distribution Company. (AEDC) and the Beninese Electricity Distribution Company (BEDC).

She also explained that Ajaokuta covers areas such as Abuja, Lokoja, Ayangba, Okene, Okpila and Benin, among others.

TCN’s efforts to overhaul circuit breakers despite routine maintenance undertaken by in-house engineers, she said, are aimed at ensuring that they continue to perform optimally and to eliminate any incidents of sudden failure due to age.

According to TCN, the exercise will be extended to all substations in the country whose circuit breakers are 20 years and older.

The transport company also explained that upgrading or replacing the circuit breakers properly will ensure their optimal functioning for the next 15 to 20 years.

“Circuit breakers protect power transformers from any abnormal condition or fault that may arise inside or outside the network.

“They also provide flexibility of supplying power to the substation switching station when maintenance is in progress, without interrupting the bulk power supply to grid distribution load centers. “

The company said it will not relax its efforts to maintain, repair and replace power transmission equipment, as well as install new ones to ensure more stable and efficient transmission of bulk electricity to electricity. nationwide distribution substations.

At the same time, the research carried out by the Center for the African Economies Studies (CSEA) found that the reliability of Nigeria’s power supply largely depends on the ability of the TCN to expand the transmission grid and absorb more electricity produced.

The study also noted that although significant funds were raised for transmission Expansion goals, TCN should carefully consider its investment options, select vital upgrades, and closely monitor spending.

The study further showed that in addition to replacing circuit breakers, monitoring control and data acquisition (SCADA), the electricity management system (EMS) and telecommunications networks would allow TCN to monitor digitally real-time network, to trace and repair the system collapse. faults and minimize the “blame game” in the industry.
