Established in 1994, Chetan Electric Pvt. Ltd. has evolved into an ISO 9001 certified global powerhouse in custom transformer design, development, and manufacturing. With over three decades of field-proven engineering excellence, our manufacturing facility in Bangalore, India, engineers robust power solutions tailored for high-demanding markets across Germany, Central Europe, and worldwide.
Every custom transformer manufactured in our facility undergoes rigorous routine testing in accordance with DIN EN 60076, IS 2026, IS 1180, and IS 11171. Furthermore, our designs are type-tested at the prestigious Central Power Research Institute (CPRI), Bangalore, validating our capability to handle severe short-circuit electromagnetic forces, extreme thermal stress, and high-voltage impulse surges required by modern European power networks.
Supplying transformers to the German industrial market requires navigating tight energy efficiency mandates (EU Ecodesign Directive 2009/125/EC Tier 2 EN 50708), strict noise emission limits, and specialized dynamic load requirements. Standard off-the-shelf transformers frequently fail when subjected to harmonic-rich environments generated by multi-pulse industrial rectifiers, arc furnaces, or variable frequency drives (VFDs).
Engineered to handle harsh cyclic thermal loads and intense electrodynamic stresses. Built with reinforced mechanical bracing, heavy-current busbar outlets, and low-flux density magnetic cores to resist saturation during furnace strike phases.
Designed for 6-pulse, 12-pulse, or 24-pulse diode/thyristor rectifiers in chemical electrolysis and DC traction systems. Incorporates phase-shifting secondary windings (e.g., Delta/Wye shifts) to neutralize harmonic distortion back to the medium-voltage grid.
Ferroresonant transformers delivering instant, automatic voltage regulation within ±1% for sensitive automated production lines in German automotive and semiconductor plants, filtering impulse spikes, brownouts, and voltage sags.

As Germany accelerates its Energiewende (Energy Transition) and pushes the boundaries of Industrie 4.0 smart manufacturing, the demands placed on electrical distribution infrastructure have never been more acute. Chetan Electric’s special application transformers are tailored to seamlessly integrate into local German operating environments.
With thousands of MW of utility-scale solar farms connected to 20kV/33kV grids, our step-up step-down oil transformers feature low no-load losses (A0 tier equivalent) and integrated On-Load Tap Changers (OLTC) to stabilize rapid voltage swings caused by intermittent cloud cover.
Installed in key industrial hubs in Baden-Württemberg and Lower Saxony, our Cast Resin Dry-Type units feature Class H insulation and partial discharge rates under 10 pC, eliminating fire risk in enclosed indoor factory environments while serving robotic welding cells and VFD drives.
Hydrogen production requires continuous, high-current DC electricity. Chetan Electric’s multi-phase rectifier transformers step down high voltage (20kV/33kV) to heavy-amperage low voltage with phase-shifted dual secondaries, minimizing harmonic feedback into public transmission lines.
Fast-charging parks along the Autobahn network require compact 1000kVA - 2500kVA distribution units capable of handling dynamic load spikes. Our pad-mounted, low-noise transformers utilize synthetic biodegradable fluids, safe for installation near municipal water protection areas (Wasserschutzgebiete).
To market electrical transformers successfully in Germany, strict adherence to European Union directives is mandatory. Chetan Electric prioritizes compliance with current and emerging European market standards:
Our transformer designs enforce max load and no-load loss thresholds ($P_k$ and $P_0$) mandated by Tier 2 standards, substantially lowering operational lifetime energy costs and carbon footprint for German asset owners.
Engineered for seamless medium-voltage and high-voltage grid connection across German Transmission System Operators (TSOs) like Amprion, TenneT, 50Hertz, and TransnetBW.
Optional filling with synthetic or natural ester oils (such as MIDEL 7131) offers K-class fire safety (flash point > 300°C) and 100% eco-biodegradability, avoiding soil/water contamination risks.
