What MS Resistances does
MS Resistances is a France-based, privately held specialist manufacturer of custom-engineered high-voltage resistors, headquartered in Saint-Chamond. Founded with over 25 years of operating history (firmographic founding year stated as 1952, with the company's own materials referencing a 2000-era restart and 35+ years of team experience), the firm designs, produces, and sells Neutral Grounding Resistors, Harmonic Filter Resistors, Load Banks, Braking Resistors, and Pre-insertion/Discharge Resistors, supported by a complementary accessories range that includes current and voltage transformers up to 36 kV, off-load disconnectors, surge arrestors, and neutral earthing cubicles.
Its technology stack rests on three modular resistor platforms — R and C Grids (precision-cut/stamped metal sheets tuned by alloy, thickness, and cut pattern), JF Grids, and SCE(N) wirewound elements (stainless steel wire on ceramic cores encapsulated in cement and silicone, with resistance up to 5 kΩ and voltage withstand up to 20 kV per element). Manufacturing is governed by an ISO 9001:2015 quality system (valid 2024–2027) with 70+ verification checkpoints per unit and full traceability from raw materials through packaging.
The business model is one-time, project-based B2B sales of custom-engineered hardware priced via quote against customer specifications, sold through direct enterprise engagement to major utilities, transmission system operators, OEMs (Hitachi, GE, ABB, Siemens Energy, Toshiba), and industrial clients across 70+ countries. Customer segments span power utilities and grid operators (primary), marine and maritime propulsion, and power electronics / FACTS systems (HVDC, MSCDN, SVC, STATCOM). Revenue is generated entirely through one-time hardware sales; there are no subscriptions, licensing, or service contracts disclosed, and no publicly available pricing.

MS Resistances product offering
Product offeringCore offering
MS Resistances designs, manufactures, and sells 100% custom-engineered high-voltage resistors, including Neutral Grounding Resistors, Harmonic Filter Resistors, Load Banks, Braking Resistors, and Pre-insertion/Discharge Resistors, for power utilities, marine, and industrial applications. Production uses three core technology families — resistor grids, resistor strips, and wirewound resistor elements — supporting parameters from high continuous power absorption to very high resistance values and voltage withstand.
Product overview
MS Resistances is a specialist in high voltage resistors, offering a portfolio of custom-engineered products designed for demanding industrial applications. The core product lineup includes five main resistor types: Neutral Grounding Resistors (NGR) for fault current detection and limiting in three-phase power systems; Harmonic Filter Resistors for absorbing harmonic currents and network distortion control; Load Banks for simulating electric loads in testing applications; Braking Resistors for dissipating kinetic energy in electrical propulsion systems; and Pre-insertion/Discharge Resistors for transient limiting during circuit energization. All products are 100% custom-engineered to meet specific technical requirements, and the company also provides complementary accessories including current transformers, voltage transformers, disconnectors, and surge arrestors. Technologies employed include resistor grids, resistor strips, and wirewound resistor elements, enabling performance characteristics from high continuous power absorption to very high resistance values (up to 5 kΩ per element) and voltage withstand (up to 20 kV per element).

Products and services
- Neutral Grounding Resistors (NGR) / Neutral Earthing Resistors (NER)
- Harmonic Filter Resistors Custom-engineered resistors used to absorb harmonic currents and limit distortion transmitted to the network. They adjust the quality factor of filters and must sustain critical parameters including power (from one to several MW), BIL (basic impulse level), and ohmic value. Deployed in HVDC, MSCDN, SVC, and STATCOM applications for power electronics and FACTS system integrators.
- Load Banks Custom-engineered devices that simulate electric loads for factory testing of diesel generator sets, reduction of wet stacking problems, periodic exercising of stand-by generator sets, UPS and battery testing, load optimization, and turbine factory tests. Available in resistive, reactive, and capacitive types with natural or forced cooling options. Intended for power generation, UPS, and industrial testing applications.
- Braking Resistors Custom-engineered resistors that dissipate kinetic energy when braking or stopping vessels using electrical propulsion. Can be equipped with water-coolers (using filtered or sea water) to reduce air temperature in engine room applications. Targeted at shipbuilders, marine system integrators, and operators of electrically propelled vessels.
- Pre-insertion Resistors / Discharge Resistors Custom-engineered pre-insertion resistors that limit transients during circuit energization with high resistance values and thermal mass for high energy absorption. Discharge resistors discharge various network elements with similar high energy absorption capacity. Intended for power grid and high-voltage network applications.
- Accessories (Current Transformers, Voltage Transformers, Disconnectors, Surge Arrestors, Neutral Earthing Cubicles) Supplementary components sold alongside the core resistor portfolio, including current transformers (up to 36 kV, wirewound or ring type, indoor/outdoor, single or multiple cores), voltage transformers (up to 36 kV), off-load disconnectors (manual or motor operated, various rated currents), surge arrestors, and neutral earthing cubicles with VCBs and CTs. Targeted at the same utility, transmission, and industrial customers as the core resistor range.

MS Resistances competitors and assessment
Company assessmentBroad incumbents
- ABB: Global power and automation major that supplies high-voltage equipment including grid components. Listed as a customer of MS Resistances but also manufactures competing power-quality and grid-protection solutions, making it both a channel and a potential competitor.
- Schneider Electric: Global French-headquartered electrical equipment and industrial automation major with overlapping offerings in power distribution, energy management, and grid solutions. Comparable as a broad incumbent in the same electrical equipment space MS Resistances serves.
- Mersen: French global manufacturer of electrical components including resistors, fuses, and power electronics for industrial and energy markets. Comparable as a larger incumbent with overlapping resistor product lines, though it operates across a much broader electrical components portfolio.
- Siemens Energy: Global energy technology major in transmission, generation, and grid solutions including HVDC and FACTS systems that consume harmonic filter resistors. As a named customer of MS Resistances, it represents both a key account and an incumbent that could vertically integrate similar capability.
- Vishay Intertechnology: Global manufacturer of passive electronic components including resistors, inductors, and capacitors for industrial, automotive, and energy markets. Comparable as a much larger incumbent in resistor manufacturing, though focused more on discrete and lower-voltage components than MS Resistances' custom high-voltage systems.
Direct peers
- Cressall Resistors: UK-based manufacturer of power resistors, neutral earthing resistors, and load banks for utility, rail, and industrial applications. Directly comparable to MS Resistances in product mix, customer base (utilities, OEMs), and custom-engineered high-power resistor focus.
- Ohmite Manufacturing: US-based manufacturer of resistive products including wirewound, thick film, and high-power resistors for industrial and commercial applications. Comparable in resistor technology and custom-engineered offerings, though more diversified across lower-voltage markets.
- HVR International: European manufacturer of high-voltage resistors and neutral earthing resistors for power transmission and industrial applications. A direct competitor to MS Resistances in NGR and high-voltage resistor segments, with similar custom-engineering approach.
- Post Glover Resistors: US-based specialist in neutral grounding resistors, dynamic braking resistors, and load banks for utility, transit, and industrial markets. Overlaps directly with MS Resistances' NGR, braking resistor, and load bank offerings.
- Hilkar: Turkish manufacturer of high-voltage neutral grounding resistors, load banks, and harmonic filter resistors serving utilities and industrial customers. Closely matches MS Resistances' core NGR and harmonic filter product lines and target verticals.
