Custom OEM/ODM Solutions Engineered to Technical Grid Standards (CAMMESA / ENRE / IEC 60076 / IS 2026)
Suppressing Harmonic Resonance and Optimizing Power Quality in High-Distortion Industrial Environments
Modern electrical networks across Argentina are undergoing unprecedented transformation. As heavy industrial facilities adopt Variable Frequency Drives (VFDs), arc furnaces, battery energy storage systems (BESS), and large-scale lithium processing equipment, non-linear electrical loads have skyrocketed. This shift introduces significant harmonic current pollution into low-voltage (380V/220V) and medium-voltage (13.2kV / 33kV) power distribution systems.
When standard power factor correction (PFC) capacitors are installed in networks dominated by non-linear loads, natural electrical resonance occurs between the grid transformer inductance and the capacitor bank. This amplifies harmonic currents (specifically 5th, 7th, 11th, and 13th order harmonics), resulting in catastrophic capacitor overheating, dielectric breakdown, unexpected circuit breaker tripping, and transformer core saturation. A Detuned Reactor (Harmonic Filter Reactor) connected in series with power capacitors is the definitive engineering solution required to shift the resonant frequency of the system below the lowest dominant harmonic frequency.
Designed primarily for networks with medium harmonic distortion dominated by 5th and 7th harmonics. Commonly paired with 400V / 440V / 480V rated capacitors to compensate for voltage rise across the series reactor.
Engineered for high-efficiency power factor correction in environments requiring higher capacitor output while maintaining strict safety margins against 5th harmonic resonance.
Essential for heavy industrial facilities with significant 3rd harmonic (150 Hz) currents caused by single-phase non-linear loads, phase-to-neutral switched power supplies, and arc heating installations.

Custom OEM/ODM Reactors Tailored to CAMMESA Regulations & Harsh Regional Operating Conditions
Argentina presents a unique power environment characterized by vast geographical distances, extreme environmental conditions, and strict utility grid codes enforced by CAMMESA (Compañía Administradora del Mercado Mayorista Eléctrico) and ENRE (Ente Nacional Regulador de la Electricidad). Industrial facilities across Argentina face aggressive financial penalties if their displacement power factor ($\cos \phi$) falls below 0.95 or if Total Harmonic Distortion of Voltage ($THD_v$) exceeds 5% at the Point of Common Coupling (PCC).
Operating in the high-altitude Puna region (3,000 to 4,500 meters above sea level), lithium brine extraction and processing plants utilize heavy-duty Variable Frequency Drives (VFDs) for pump stations and chemical evaporators. Standard reactors fail in these conditions due to reduced air density and severe thermal derating.
OEM Customization: We engineer high-altitude rated detuned reactors featuring Class H insulation, reinforced vacuum pressure impregnation (VPI), optimized cooling ducts, and oversized magnetic cores to prevent saturation under extreme temperature fluctuations.
Upstream crude extraction and natural gas processing facilities rely heavily on Electric Submersible Pumps (ESPs) and large compressor stations driven by high-power thyristor converters. These loads inject high levels of 5th and 11th harmonics into weak localized grid connections.
OEM Customization: Heavy-duty iron-cored dry-type reactors housed in IP54 outdoor enclosures, engineered to withstand abrasive dust, wind storms, and continuous 24/7 harmonic stress.
As one of the world's largest agricultural export hubs, the Parana River port belt operates massive grain elevators, oilseed crushing mills, and conveyor networks. Frequent motor start/stop cycles create dynamic reactive power demands and transient harmonic bursts.
OEM Customization: Fast-switching detuned reactor modules integrated with automatic power factor compensation (APFC) step controllers, minimizing grid wear and eliminating CAMMESA reactive power surcharges.
Automated automotive assembly plants, robotic welding cells, and steel processing facilities experience high voltage distortion and instantaneous power factor drops that disrupt sensitive CNC electronics.
OEM Customization: Precision-tuned low-loss copper wound reactors featuring low sound levels (< 55 dB) and integrated micro-switches for thermal protection against overload conditions.
Strategic Drivers Shaping Power Quality and Electrical Equipment Sourcing
Regulatory bodies in Argentina are expanding continuous power quality metering at industrial connection points. Penalties for low power factor and excessive harmonic injection have increased significantly, compelling plant managers to retrofitting existing fixed capacitor banks with tuned and detuned filter reactors.
With massive solar plant deployments in Cuyo and wind farms in Patagonia, industrial off-takers connecting to the SADI (Sistema Argentino de Interconexión) must maintain pristine grid harmony. Detuned reactors are indispensable for stabilizing voltage profiles during variable generation periods.
Argentinian procurement engineers are increasingly shifting away from off-the-shelf distributor items in favor of direct factory OEM custom engineering. Direct factory collaboration ensures exact physical dimensional matching for retrofit enclosures, customized tap settings, and optimized freight cost efficiency.

Established in 1994, Chetan Electric Pvt. Ltd. is an ISO 9001 certified global leader in the design, development, and custom manufacturing of power distribution transformers, specialized dry-type transformers, and iron-cored reactors up to 1000 KVAR. Headquartered in Bangalore’s premier industrial zone, our state-of-the-art facility serves over 600 loyal enterprise clients across real estate, heavy infrastructure, aerospace, defense, and international mining sectors.
Our products undergo comprehensive type testing at the world-renowned Central Power Research Institute (CPRI). Every single OEM detuned reactor and distribution unit is subjected to routine testing in full compliance with IS 2026, IS 1180, IS 11171, and IEC 60076-6 standards before shipment.

Our reactors deliver linear inductance characteristics up to 1.8 to 2.2 times rated current without magnetic saturation.
Technical, Commercial, and Logistics Guidance for Importing OEM/ODM Equipment
We manufacture custom reactors for standard Argentinian low-voltage supply systems (380V / 220V 50 Hz), as well as dedicated nominal voltages of 400V, 415V, 440V, 480V, and 690V. Medium-voltage iron-cored reactors are available for 13.2kV and 33kV network distribution.
For installations above 1,000 meters in the Andes region, reduced air density impairs cooling efficiency and dielectric withstand voltage. We re-engineer the winding temperature rise allowance, increase creepage distances, and oversize the magnetic core frame to ensure full rated output at altitudes up to 4,500m ASL without thermal breakdown.
Connecting a reactor in series with a capacitor creates a boost in terminal voltage across the capacitor bank. For a 380V grid with a 7% detuned reactor ($p=7\%$), the capacitor voltage rises to approximately 409V. Therefore, we specify capacitors rated for at least 440V or 480V to prevent premature dielectric failure.
