Current Transformer Solutions for Power Projects in Africa: How Split and Ring Current Transformers Improve Power Monitoring and Their Application in Electrical Panels.
introduction
In Africa, electricity infrastructure is undergoing rapid transformation. From commercial solar power plants and industrial installations to low-voltage distribution networks, engineers are facing increasing demands for reliable energy metering, energy management, and electrical protection.
For electrical equipment manufacturers, electricians, and system integrators, selecting the right current transformer is crucial. A suitable current transformer not only ensures accurate current measurements but also improves the reliability and efficiency of the entire electrical system.
However, energy projects in Africa often face specific challenges:
Upgrades to existing electrical systems should be carried out without causing long-term service interruptions.
Solar and renewable energy projects require accurate monitoring of electricity consumption.
Industrial enterprises require continuous energy management.
Control panel manufacturers require compact and reliable components for low-voltage control panels.
To address these challenges, HEYI offers two practical solutions in the field of computed tomography:
These two products have been developed for different application scenarios within Africa’s ever-evolving energy infrastructure.
1.1 Solar energy projects require accurate energy monitoring.
Many African countries, including Kenya, South Africa, Tanzania, Nigeria and Egypt, are investing heavily in solar energy systems.
A typical commercial solar project includes:
At the output and distribution end of the inverter, engineers need current transformers to:
Identification of abnormal operating conditions
For engineering, procurement and construction (EPC) companies specializing in solar energy, the current transformer (CT) installed in AC distribution boards must meet the following requirements:
The DP series split core current transformers are particularly suitable for such applications as they can be installed around existing cables or busbars without interrupting the primary circuit.
Why is CT imaging with sample segmentation important for projects in Africa?
Many African factories have had electrical systems in operation for many years.
Engineers often have to add:
However, to install a regular scanner you need the following:
This process is intensified:
The dual-core CT scanner solves this problem.
The DP series is designed for connection to existing cables or busbars without interrupting the circuit. It features a wide mounting window suitable for conductors and busbars with large cross-sections, making it ideal for high-current applications.
Typical applications of serial computed tomography (CT)

Ideal for solar power system upgrade projects.
For large solar power plants, DP models support high current operation, including:
Higher personalized ratings
While the DP series is ideal for retrofit projects, the RCT series ring current transformers have been designed for new electrical equipment production.
The following areas of application are typical for African home appliance manufacturers:
Typical structure:
Why do electrical device manufacturers choose ring CT scanners?
When designing a new electrical panel, engineers typically prefer the following options:
The RCT series offers a traditional ring-shaped CT structure suitable for the following applications:
Current measure
Hear
security applications
The RCT series is designed for low voltage current measurements with a nominal frequency of 50/60 Hz and current ranges covering various industrial requirements.
For African electrical engineers, the choice may be simple:
| Application | TC recommended |
| Modernization of an existing plant | Split-core computed tomography (SCCT) |
| Modernization of the energy consumption monitoring system | Split-core computed tomography (SCCT) |
| Solar photovoltaic system modernization project | Split-core computed tomography (SCCT) |
| Production of new low-voltage switching equipment. | TC Ring RCT |
| MCC panel production | TC Ring RCT |
| Distribution cabinet | TC Ring RCT |
5.1 Easy installation
Many African projects require reduced installation time.
Dual-core computed tomography allows:
5.2 Wide current range
Different projects require different power levels.
From small commercial systems to industrial installations, engineers require flexible solutions.
The DP series supports:
Depending on application requirements, the product can be individually adapted with different output signal types such as 1A, mA and mV.
5.3 Compatibility with modern energy management systems
African industries are increasingly gaining ground:
CT scanners are evolving to become not only measuring instruments but also important data collection devices.
HEYI specializes in providing reliable current measurement solutions in the following fields:
Companies engaged in the engineering, procurement and construction (EPC) of solar energy systems.
Our computed tomography (CT) solutions help engineers:
