CEMarked CEMarked High-efficiency components engineered to mitigate supply-line transients, dampen harmful switching harmonics, and safeguard automation logic controllers across sensitive production lines.
Hungary has consolidated its status as an advanced European manufacturing corridor, driven by intensive Foreign Direct Investment (FDI) across the automotive powertrain, EV lithium-ion battery manufacturing, chemical processing, and robotic assembly sectors. From the established industrial centers of Győr, Kecskemét, and Esztergom to massive ongoing greenfield developments in Debrecen, modern production plants require high-performance low-voltage (LV) and medium-voltage (MV) automation switchgear. Industrial automation panels built for these operations must deliver uninterrupted reliability under severe electromagnetic stress, harmonic pollution, and continuous mechanical cycling.
As equipment builders and Engineering, Procurement, and Construction (EPC) contractors design power distribution centers (PDC), motor control centers (MCC), and PLC-based supervisory cabinets, component selection determines operational longevity. Prima Transformers, drawing upon a 25-year manufacturing pedigree originating from our parent group Prima Automation (India) Pvt. Ltd. (established in 1990), supplies specialized magnetics, reactors, and voltage conditioning equipment explicitly engineered to withstand the demanding load profiles of European Industry 4.0 infrastructure.
Gigascale cell synthesis and cathode assembly facilities operate sensitive automation racks surrounded by high-power induction furnaces, slurry mixers, and electrode slitters. Our low-inrush galvanic isolation transformers and high-frequency DC smoothing reactors suppress DC bus ripple and shield PLC digital I/O lines from devastating inductive ground loops.
Automated robotic welding fixtures, conveyor drives, and CNC machining centers generate heavy harmonic feedback and rapid voltage drops. Our VFD input/output line reactors (rated up to 2500A) and servo-driven AC voltage stabilizers protect servo amplifiers and reduce thermal degradation across inverter IGBT bridges.
Continuous continuous-process polymer and specialty chemical reactors require panel architectures conforming to strict thermal and hazardous-area safety baselines. Benefiting from our parent company’s experience in pressurized, flameproof, and intrinsically safe control panels, our dry-type and cast resin transformers ensure minimal fire loading and maintenance-free uptime.
Hungarian distribution system operators (DSOs) such as MVM Démász and E.ON Hungária strictly enforce grid injection limits for Total Harmonic Distortion (THD-I and THD-V). Incorporating tuned DC link chokes and line reactors upstream of multi-axis variable frequency drives is now mandatory to preserve power factor and prevent substation capacitor overheating.
European Union energy efficiency mandates demand radical reductions in load and no-load core losses for power and isolation transformers. Our specialized S20 and dry-type magnetic cores are fabricated from prime grade, cold-rolled grain-oriented (CRGO) electrical silicon steel, maximizing magnetic permeability while minimizing baseline thermal emission inside enclosed MCC panels.
Modern machine builders prioritize smart diagnostic panels. Our transformers can be configured with PT100 resistance temperature detectors, bi-metallic trip contacts, and electrostatically shielded windings that integrate cleanly with SCADA network telemetry, enabling Hungarian maintenance engineers to forecast insulation degradation before catastrophic breakdown occurs.

Operating from our dedicated 5,500 m² high-capacity production facility located in Santej, Ahmedabad (Gujarat, India), Prima Transformers combines modern automated coil winding machinery with computer-controlled testing stations. Drawing synergy from our parent enterprise, Prima Automation (India) Pvt. Ltd., which has engineered turnkey PLC, SCADA, and hazardous-area control systems since 1990, every component we build reflects a machine-builder’s operational insight: optimal wiring clearance, high-torque industrial terminals, robust mechanical shock tolerance, and dependable thermal margins.
Every individual unit undergoes computerized no-load and full-load characterization to definitively quantify core loss, copper loss, and impedance voltage matching prior to crating.
Inter-turn and layer-to-layer dielectric endurance is validated at elevated excitation frequency and doubled operational voltage, preventing flashovers caused by steep switching transients.
High-voltage breakdown stress testing (up to 5kV AC RMS) paired with automated Megger insulation resistance measurements guarantees absolute galvanic safety across control circuits.
Digital LCR instrumentation and milli-ohm winding meters verify phase balance and exact magnetic inductance values, ensuring line reactors match drive impedance requirements perfectly.
Yes. All transformers, reactors, and voltage regulators exported to Hungary and the broader European Union carry the CE mark and conform strictly with relevant harmonized standards, including EN 61558-1/EN 61558-2 (safety of power transformers and power supply units) and EN 60076 (power transformers). Full Declaration of Conformity documents and routine factory test certificates are provided with every batch.
When selecting control power transformers for European automation panels, we calculate the combined sealed holding VA and peak instantaneous inrush VA of all simultaneously energizing AC contactors and solenoid valves. By engineering low-leakage magnetic paths and using high-saturation core laminations, our transformers limit secondary voltage drop to under 5% during inrush, eliminating relay contact chatter.
Our units are wound specifically for standard Hungarian distribution networks (400V three-phase / 230V single-phase, 50Hz). In addition, we configure primary multi-taps (±2.5%, ±5%) to adjust for local substation voltage variations and construct custom vector groups (such as Dyn11, Dyn5, or Dzn0) to align with plant-specific grounding schemes.
Products are crated in seaworthy, ISPM-15 heat-treated fumigated wooden cases lined with heavy-gauge moisture-barrier foil and industrial silica desiccant bags. Coils and core assemblies are vacuum-pressure impregnated (VPI) with Class H insulating varnish to prevent internal moisture ingress during multi-week intermodal transit through Adriatic ports (e.g., Koper or Rijeka) directly to Budapest and regional hubs.
Yes. We frequently build custom footprints, low-profile horizontal configurations, and specialized terminal layouts to fit compact Rittal, Schneider Electric, or custom metal enclosures. Our mechanical engineering department shares full 3D STEP and DWG models during quotation to streamline panel layout integration.
To provide an exact engineering proposal, please share: rated capacity (VA, kVA, or kW), primary and secondary voltages, phase configuration, operating frequency (50Hz), duty cycle, insulation class requirement, IP rating for enclosures (if needed), and any specific DSO or customer test specifications.
