4 Questions to Help You Find the Best Current Transformers
What could be worse than arriving at a site to install a meter only to find that you are not equipped with the appropriate current transformer (CT)? As the saying goes, a craftsman is only as great as his tools; not having the right ones is not only a waste of time but also money. However, itentirely avoidable if you pre-plan this the right way.
Today you can easily find a current transformer available in a variety of sizes, styles, and amperage ranges. Some of them also vary in terms of accuracy and output as well. With so many variables, it is often challenging to choose the right transformer for a project.
However, selecting the right current transformer can be simplified by answering a few questions about your goals, site, and the project in hand. In fact, you may be able to straighten out of some of these details even before checking out a project site! That said, let us look at some basic questions that you must answer to choose the right option and save yourself plenty of troubles down the road!
What Power Meter Are You Using?
You need to understand that because a CT agrees with a meter doesn’t mean that it is your best option. In fact, your meter choice has a considerable impact on your CT choice.
So, you need to check if your meter is better for mV output CT or amp output? You must also check if the meter will be installed permanently, or are you planning to move the meter from one location to another?
How Many Amps Do You Want To Measure?
Another important consideration is to know the number of amps that will be measured. This is something you are likely to know before you visit your site because it is something determined by the goals of your project. For example, if your purpose is to measure a lighting load in a small office, then the CT requirement will be relatively smaller compared to the one for a large establishment.
It is also important to keep in mind that CT performs best when the current flow is anywhere between 10-100% of the CT full-scale value. It would help if you also considered Rogowski coils that are easy to install and work with a wide range. It is also critical to keep in mind that you get the maximum CT accuracy when the load operates to CT’s full rating possible. If the load is under 20A, then it is not advisable to use Rogowski coil because it will be too huge for the load.
If you be moving the meter between multiple loads, then the best solution is to keep at least two different sets of CTs in your repository – one for the small load and one for a large load. This way you will remain covered for all kinds of project settings.
What Are Your Project Types And Goals?
If you are thinking about your project type and goals, then it is essential to know the purpose of the end data. For instance, if you are planning to do a measurement and verification project (M&V), then a standard accuracy meter will be enough to reach your project requirements. However, if you use a revenue-grade meter for tenant submetering, then you need a maximum amount of accuracy. This is when a revenue grade CT would be a perfect choice.
What Is The Duration Of Your Project?
If you are planning to move the meter around a lot, then split-core, clamp-on, and Rogowski coil CTs can be a bit inconvenient to uninstall. In any case, regardless of the CT you choose, it is always advisable to first de-energize the circuit and follow complete safety precautions in your manual to move the CT safely.
If you have read enough and still feel unsure about the best CT for your project, then don’t hesitate to take help from an expert. Just discuss your project requirements and let them help you choose the right CT tailored to your needs.
The Central Bank of Nigeria (CBN) yesterday said 33 banks have met new minimum capital requirements under its recapitalisation programme, raising a combined N4.65 trillion to strengthen the financial system.
The apex bank disclosed this in a statement marking the end of the exercise, which commenced in March 2024 and drew participation from domestic and foreign investors.
The statement was jointly signed by the Director of Banking Supervision, Olubukola Akinwunmi, and the Acting Director of Corporate Communications, Hakama Sidi-Ali.
The statement said “Over the 24-month period, Nigerian banks raised a total of N4.65tn in new capital, strengthening the resilience of the financial system and enhancing its capacity to support the economy.”
The regulator said local investors accounted for 72.55 per cent of the funds, while international investors contributed 27.45 per cent, reflecting continued confidence in the sector.
Commenting on the outcome, the CBN Governor, Olayemi Cardoso, said in the statement, “The recapitalisation programme has strengthened the capital base of Nigerian banks, reinforcing the resilience of the financial system and ensuring it is well-positioned to support economic growth and withstand domestic and external shocks.”
It added that while 33 banks have complied with the new thresholds, a few others are still undergoing regulatory and legal processes.
The statement noted, “The CBN confirms that 33 banks have met the revised minimum capital requirements established under the programme.
“A limited number of institutions remain subject to ongoing regulatory and judicial processes, which are being addressed through established supervisory and legal frameworks.
“All banks remain fully operational, ensuring continued access to banking services for customers.”
The apex bank stressed that the exercise was executed without disrupting banking operations, ensuring uninterrupted access to services nationwide.
It further stated that key prudential indicators have improved, particularly capital adequacy ratios, which remain above global Basel benchmarks.
The minimum ratios were set at 10 per cent for regional and national banks and 15 per cent for banks with international licences.
The bank also said the recapitalisation coincided with a gradual exit from regulatory forbearance, a move it said improved asset quality, strengthened balance sheet transparency, and enhanced overall stability.
To preserve these gains, the CBN said it has reinforced its risk-based supervision framework, mandating periodic stress tests and adequate capital buffers for banks.
It added that supervisory and prudential guidelines would be reviewed regularly to strengthen governance, risk management, and resilience across the sector.
“The successful completion of the programme establishes a stronger and more resilient banking system, better positioned to support lending, mobilise savings, and withstand domestic and global shocks,” the statement said.
The Tide learnt that foreign capital inflows into Nigeria’s banking sector rose by 93.25 per cent year-on-year to $13.53bn in 2025, up from $7.00bn recorded in 2024, amid the ongoing recapitalisation drive by the Central Bank of Nigeria.
Data from the National Bureau of Statistics capital importation report showed that the banking sector remained the dominant destination for foreign capital, accounting for $13.53bn of the total $23.22bn recorded in 2025, representing 58.26 per cent of total inflows, up from 56.81 per cent in 2024.
The surge reflects heightened investor interest in Nigerian banks as they raised fresh capital to meet new regulatory thresholds introduced by the apex bank, with industry-wide recapitalisation activities driving large-scale inflows across all quarters of the year.
However, the Centre for the Promotion of Private Enterprise (CPPE) recently raised concerns over weak credit flows to small businesses despite recent banking sector reforms.
The CPPE, led by a renowned economist, Dr Muda Yusuf, acknowledged that the ongoing bank recapitalisation exercise by the CBN has strengthened the financial system, but warned that the benefits have yet to translate into meaningful support for the real economy.
The facility will be disbursed through participating Microfinance Institutions (MFIs), which will in turn extend the loans to their customers, particularly SMEs, as they directly interface with businesses at the grassroots level.
The Executive Director of COMCIN, Mr. Micheal Ogbaa who represented the Chairman, Dr. Iredele Oyedele (FCA, FCCA), said the initiative is designed to strengthen micro-lending institutions and expand access to finance for grassroots entrepreneurs, particularly women and youths in the informal sector.
Ogbaa explained that COMCIN does not lend directly to individuals but works through its network of microfinance and cooperative institutions, which in turn provide loans to end users.
“We came together to advocate for the microfinance ecosystem. Commercial banks often exclude people at the grassroots, but our members are positioned to reach them. This facility will empower them to do more,” he said.
He noted that the loan scheme offers low interest rates and flexible repayment plans, making it more accessible to small business owners.
According to him, about 90 percent of beneficiaries are expected to be women, who play a key role in sustaining families and driving economic activities at the local level.
“Our focus is on traders, service providers, and players in the informal sector. These are the real movers of the economy. By supporting them, we are strengthening families and contributing to national development,” he added.
Ogbaa disclosed that eligible SMEs with proven integrity and business track records could access up to N5 million each through participating micro-lending institutions. The rollout has commenced in Lagos and will extend to Abuja, Enugu, and other regions, including the South-West, South-East, and North-East.
He said 12 micro-lending institutions have already benefited from the scheme, while 85 applications are currently being processed under the pilot phase.
“Our target is to reach at least 100,000 SMEs nationwide. We are building a platform that connects funding partners with credible micro-lending institutions, creating a reliable channel for financial inclusion,” Ogbaa said.
He added that COMCIN is also working to attract larger funding pools from development finance institutions and private investors, noting that successful implementation of the pilot phase would boost confidence and unlock more capital for SMEs.
“We have seen encouraging testimonies from early beneficiaries. As we demonstrate transparency and efficiency, more institutions will be willing to channel funds through us,” he said.
