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 three-phase line, input and output chokes 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 inductance and current rating matched to your drive.
A three-phase line choke is an inductor connected in series with a drive or rectifier. On the input side it reduces harmonic current and protects the drive from line spikes and notching. On the output side it limits dv/dt and protects motors fed through long cables.
For drive users in Kolkata, a line choke on the input or output of a VFD reduces harmonics, limits inrush and protects the drive and motor from spikes and long-cable effects.
Reduce harmonic distortion and electrical noise on drive and rectifier supplies.
