High-Performance Industrial Transformers

Chetan Electric Pvt. Ltd. is a premier global manufacturer of custom-engineered power and distribution transformers based in Bangalore, India. Backed by over 30 years of technical expertise, our solutions are engineered in compliance with international standard specs including IS 2026, IS 1180, and IS 11171. All units are CPRI type-tested, delivering exceptional thermal efficiency, robust short-circuit withstand capabilities, and long-term operating reliability for demanding global B2B industrial procurement.

Oil Cooled Transformers

Our oil-immersed power and distribution transformers are engineered up to 5000 KVA at 33kV. Manufactured using prime-grade electrolytic copper/aluminum conductors and high-permeability cold-rolled grain-oriented (CRGO) silicon steel cores to strictly minimize core losses. Available with Off-Circuit Tap Changer (OCTC) or On-Load Tap Changer (OLTC) complete with Remote Tap Changer Cubicle (RTCC) and Automatic Voltage Relay (AVR) for seamless grid regulation under fluctuating industrial loads.

  • Voltage Class: Up to 33kV / Capacity up to 5000 KVA
  • Cooling Types: ONAN / ONAF Forced Cooling
  • Standards: Tested & Approved per IS 2026 / IS 1180

Dry Type Transformers

Designed specifically for critical indoor installations, high-rise commercial complexes, underground projects, and environmental safety-sensitive plants. Featuring Vacuum Pressure Impregnated (VPI) or Cast Resin Dry Type (CRT) construction with Class F / Class H thermal insulation. Engineered to sustain a 90°C temperature rise in windings while delivering flame-retardant, self-extinguishing, and moisture-resistant operation without environmental oil pollution risk.

  • Voltage Class: Up to 11kV Indoor Systems
  • Insulation Rating: Class F (155°C) / Class H (180°C)
  • Standards Compliance: IS 2026 & IS 11171 / IEC 60076

Special Application Transformers

Purpose-built electrical transformers custom engineered to meet harsh industrial operational cycles. Our portfolio includes heavy-duty Industrial Arc/Induction Furnace Transformers designed for continuous high-current thermal stress, Rectifier Transformer Equipment for DC power conversion, High Voltage Testing Transformers (up to 150kV) for power frequency testing laboratories, and Motor Starting Autotransformers.

  • Applications: Furnace, Rectifier, High-Voltage Testing
  • High Harmonic & Short-Circuit Surge Resilient
  • Custom Primary/Secondary Voltage Tap Configurations

Constant Voltage Transformers (CVT)

Utilizing ferroresonant voltage regulation technology, Chetan Electric CVTs deliver instantaneously stabilized sine-wave AC voltage output over extreme input mains fluctuations. Providing total galvanic isolation between input mains and sensitive load circuits, effectively shielding mission-critical automation systems, medical instrumentation, data telemetry, and laboratory controls against spikes, harmonics, and electrical noise.

  • Ferroresonant Ultra-Fast Output Regulation (±1%)
  • Complete Electrical Isolation & Spike Attenuation
  • Solid-State Construction with No Moving Parts
