Kolkata anchors East India's industry. Howrah's engineering units, the Dankuni and Uluberia industrial parks, and the Durgapur and Haldia belts serve steel, power, port and process industries across the region.
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 delivered by road to customers in Howrah, Dankuni, Taratala and across Kolkata.
Rated for 230 V single-phase / 415 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 Kolkata, 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.
