Medium Voltage Inductances: Enhancing Reliability and Grid Protection

In the realm of high-power electrical systems, managing energy quality and safeguarding infrastructure are non-negotiable priorities. Medium voltage inductances (often referred to as reactors) serve as the first line of defense against electrical disturbances, ensuring that sensitive equipment remains operational under demanding conditions.

At EREMU, we leverage over 60 years of expertise in the design, manufacturing, and repair of electrical equipment to deliver medium voltage solutions that exceed international performance standards.

Why Are Medium Voltage Inductances Critical?

As modern grids integrate more variable renewable energy and complex electronic drives, the risk of instability increases. Our medium voltage inductances are engineered to provide several vital functions:

Harmonic Filtering: They reduce harmonic distortion in MV networks, preventing overheating in capacitor banks and ensuring a clean sine wave.
Short-Circuit Current Limiting: By acting as a high-impedance barrier during faults, these inductances protect circuit breakers and busbars from catastrophic mechanical stress.
Transient Damping: They mitigate voltage spikes caused by switching operations, protecting the insulation of motors and transformers.
Current Smoothing: Essential in power conversion systems to minimize ripple and provide a stable DC output after rectification.

Bespoke Engineering and Manufacturing

At EREMU, we don’t believe in “one-size-fits-all” components. Every industrial environment has unique constraints—be it space, temperature, or specific electrical loads.

Customized Design: We manufacture inductances using high-conductivity copper or aluminum, utilizing Class F or H thermal insulation to ensure a long service life in high-temperature environments.
Environmental Protection: Whether you need an indoor unit for a switchgear cabinet or an outdoor solution resistant to extreme weather and corrosion, we adapt the enclosure and protection (IP) levels accordingly.
Certified Quality: All our equipment is rigorously tested in our laboratory under international standards (IEC, UNE, EN), ensuring total compliance and safety.

Specialized Repair and Maintenance

Our identity as a repair specialist gives us a unique edge. We don’t just know how to build a unit; we know exactly how they fail. This “reverse engineering” knowledge allows us to:

Extend Equipment Life: We offer professional rewinding and insulation restoration for medium voltage inductances of any brand.
Reduce Downtime: Our technical team provides rapid diagnostic and repair services, ensuring your critical processes are back online as soon as possible.
Technical Upgrades: During the repair process, we can often improve the original design to better handle the specific stresses of your installation.

Global Applications

EREMU’s medium voltage inductances are trusted across sectors where energy continuity is a lifeline:

Renewable Energy: Filtering for wind and solar farms.
Heavy Industry: Steel mills, mining operations, and chemical plants.
Infrastructure: Power distribution substations and railway traction systems.
