At Chetan Electric Pvt. Ltd., we specialize in the custom engineering and manufacturing of heavy-duty special application transformers tailored to rigorous industrial requirements. Operating under harsh electrical, thermal, and mechanical conditions, special transformers require specialized design expertise far beyond standard power distribution units.
With over 30 years of engineering experience since 1994, our specialized transformers are designed to withstand severe short-circuit forces, extreme harmonic loads, and frequent voltage fluctuations. Every unit is manufactured at our Bangalore facility and subjected to stringent quality verification, including full type testing at the renowned Central Power Research Institute (CPRI).
Type-tested for short-circuit withstand & impulse voltage integrity at CPRI labs.
Fully compliant with IEC 60076, IS 2026, IS 1180, and IEEE guidelines.
We provide fully customized electrical solutions for metallurgy, chemical electrolysis, high-voltage testing laboratories, and heavy motor starting systems.
Engineered for steel works, arc furnaces, and induction melting operations. Built to handle extreme thermal stress, heavy low-voltage secondary currents, and frequent operational short circuits.
Designed for chemical electrolysis, metal refining, traction systems, and DC industrial drives. Integrated with semiconductor rectifier bridges for harmonic minimization and high continuous DC output.
Precision-built power frequency high voltage testing transformers engineered for electrical testing laboratories, cable testing, insulation breakdown analysis, and research institutes.
Below are standard technical ranges. All units are fully customized to buyer-specific mechanical, spatial, and electrical requirements.
