South Africa has Africa's most developed manufacturing, mining and automotive industries. Years of load-shedding have made backup power, solar and inverter systems mainstream, so demand for UPS and inverter transformers, chokes and harmonic reactors is strong.
VA Electricals designs and manufactures toroidal current transformers at its works in Bhosari, Pune. Every unit is built to your voltages and rating and tested in-house, then packed for export to buyers in Johannesburg, Ekurhuleni, Pretoria and across South Africa.
Rated for 230 V single-phase / 400 V three-phase, 50 Hz systems, with ratios selected to suit your meters, relays and protection scheme.
A current transformer (CT) produces a secondary current proportional to the current in a primary conductor, so meters, relays and controllers can measure high currents safely. VA Electricals makes toroidal CTs, whose ring shape uses space and material efficiently to give compact, accurate and cost-effective units.
In South Africa, our CTs feed energy meters, protection relays and monitoring systems in LT panels, inverters and power electronics.
Compact, efficient ring-type CTs for metering and current sensing.

Platinum, gold and coal mines in Gauteng, North West and Mpumalanga run pumps, hoists and conveyors.
Typical use: Current measurement for metering, protection and energy monitoring.
Load-shedding has driven rapid growth in rooftop solar, battery and inverter systems.
Typical use: Current sensing in solar inverters and combiner panels.
Vehicle plants in Gqeberha, Durban and Pretoria and their suppliers run large production lines.
Typical use: Current measurement for metering, protection and energy monitoring.
Panel builders in Johannesburg and Ekurhuleni supply mining, industrial and commercial projects.
Typical use: Metering and protection inputs for LT panels and energy meters.
Johannesburg and Cape Town are Africa's largest data-centre markets.
Typical use: Energy monitoring on UPS and distribution feeds.
Municipal water utilities and mines run large pumping and dewatering systems.
Typical use: Current measurement for metering, protection and energy monitoring.
Many sites in South Africa run on a mix of grid power and diesel generators, with voltage swings and frequent changeovers. Tell us your supply conditions and we design with margin on voltage, temperature rise and duty, so equipment stays protected.
