About Us
Who We Are
Engineering Excellence in Heavy-Duty Magnetics Since 2006
Prima Transformers Pvt. Ltd. was incorporated in 2006 as a 100% subsidiary and strategic diversification of Prima Automation (India) Pvt. Ltd. (founded in 1990). Established to handle the backward integration and specialized production of mission-critical magnetics, we design and manufacture CE-marked control and power transformers ranging from 50VA to 5000kVA, heavy-duty line and load reactors up to 2500A, and sine wave and harmonic filters up to 500HP.
With our parent group’s 35-year legacy of engineering PLC, SCADA, and hazardous-area certified control panels (Flameproof, Pressurized, and Intrinsically Safe), every transformer we build is developed from the rigorous perspective of an automation panel engineer. We understand real-world voltage drops, inrush thermal stresses, footprint limits, and harmonic deratings—delivering electrical robustness that international EPC contractors and machine builders rely upon.

Distinct Advantages for Overseas Procurement
How our engineering culture, production efficiency, and testing facilities protect your installation uptime.
25+ Years Engineering Leadership
Our R&D is driven by senior magnetics specialists with decades of high-level power electronics background (including Hi-Rel). We handle high-frequency harmonics, difficult ambient temperatures, and complex multi-winding requirements with mathematical precision.
Certified & Skilled Technicians
Winding, insulating, brazing, varnishing, and assembly are executed by certified ITI technicians trained under strict quality protocols. Experienced test engineers oversee full-cycle computerized inspections, preserving traceable history records.
Cost-Effective Batch Manufacturing
Through systematic production planning, bulk raw material procurement (high-grade CRGO laminations and electrolytic copper/aluminum), and lean assembly flows, we provide overseas buyers with premium-grade engineering at highly competitive pricing.
Customer Safety & IP Protection
We manufacture strictly as per IS/IEC standards using certified non-toxic, flame-retardant insulating media. Our business operates under strict non-disclosure ethics, ensuring complete confidentiality for custom OEM schematics and design files.
Integrated 5,500 m² Plant
Located in Santej (Ahmedabad's industrial hub), our manufacturing campus features heavy-duty automatic winding machines, high-capacity vacuum pressure impregnation (VPI) varnishing, large clean assembly zones, and dedicated test bays.
100% Routine Testing & Verification
Every single unit undergoes rigorous computerized open-circuit, short-circuit, double-voltage double-frequency (DVDF), and insulation resistance testing. Complete factory acceptance test (FAT) documentation accompanies every shipment.
