Expert Advocates Complete Automation Of Standby Generator
An engineering expert, Engr. Nwachukwu Alloy Iloanwusi, has called for the complete automation of a standby generator.
Engr. Iloanwusi made this known during a paper presentation at the technical section of the Nigerian Society of Engineers (NSE), Port Harcourt Branch monthly general meeting at the NSE Secretariat in Port Harcourt.
According to him, to automate a standby generator would close the gap between the time of public power failure and when the person in charge switches on the standby generator which normally causes harm in the case of life support or operation in the hospitals or intelligence meeting.
The expert stated that control of the operations of a standby generator during power outage is done by activating the prime mover at mains failure and further highlighted definition of concept on a standby generator.
He further said that “when there is a failure of public power supply, the loads are being transferred and returned to mains when power had been restored, thereby shutting down the generator as well as protecting the engine from shortage of lubricant or coolant and in that case pressure and temperature sensors are employed”.
On the load transfer circuit, the expert maintained that the change over circuit has two loads bearing contractors rated 800amp with a common output, but each serving as input for mains and standby generators respectively, recommending the 800amp to calculate load rating.
Engr. Iloanwusi noted that the control circuit has two segments of which one is controlled by mains and the other by standby, pointing out that the segment controlled by mains supplies three phase voltages and neutral to a neutral voltage monitor.
The engineer hinted that the essence of the delay is to ensure that the supply has stabilized while the essence of passing through the normal closed contact of generator contractor is to ensure that the generator contractor is de-energised.
On the engine protection circuit, Engr. Iloanwusi stated that it is made up of a circuit that would cut off the engine at the events of high temperature or low lubricant pressure, adding that it is incorporated into the stopping circuit.
He commended the good work of the present executives and the opportunity given to him during the technical session.

CBN Revises Cash Withdrawal Rules January 2026, Ends Special Authorisation
The Central Bank of Nigeria (CBN) has revised its cash withdrawal rules, discontinuing the special authorisation previously permitting individuals to withdraw N5 million and corporates N10 million once monthly, with effect from January 2026.
In a circular released Tuesday, December 2, 2025, and signed by the Director, Financial Policy & Regulation Department, FIRS, Dr. Rita I. Sike, the apex bank explained that previous cash policies had been introduced over the years in response to evolving circumstances.
However, with time, the need has arisen to streamline these provisions to reflect present-day realities.
“These policies, issued over the years in response to evolving circumstances in cash management, sought to reduce cash usage and encourage accelerated adoption of other payment options, particularly electronic payment channels.
“Effective January 1, 2026, individuals will be allowed to withdraw up to N500,000 weekly across all channels, while corporate entities will be limited to N5 million”, it said.
According to the statement, withdrawals above these thresholds would attract excess withdrawal fees of three percent for individuals and five percent for corporates, with the charges shared between the CBN and the financial institutions.
Deposit Money Banks are required to submit monthly reports on cash withdrawals above the specified limits, as well as on cash deposits, to the relevant supervisory departments.
They must also create separate accounts to warehouse processing charges collected on excess withdrawals.
Exemptions and superseding provisions
Revenue-generating accounts of federal, state, and local governments, along with accounts of microfinance banks and primary mortgage banks with commercial and non-interest banks, are exempted from the new withdrawal limits and excess withdrawal fees.
However, exemptions previously granted to embassies, diplomatic missions, and aid-donor agencies have been withdrawn.
The CBN clarified that the circular is without prejudice to the provisions of certain earlier directives but supersedes others, as detailed in its appendices.
