The Fortress Approach

Fortress designs and manufactures filter resistors to meet the unique demands of each installation. Our team engineers low-inductance systems using corrosion-resistant elements and tailored enclosures, ensuring each unit meets electrical, mechanical, and environmental requirements. All designs follow relevant IEC and IEEE performance standards for thermal and dielectric performance.

System Adaptability

No two installations are the same. Fortress works closely with EPCs, utilities, and OEMs to ensure that filter resistors are correctly specified for power conditioning, harmonic suppression, or substation integration. Whether part of a new build or retrofit, Fortress ensures compatibility with broader system infrastructure.

Use Case: Power Quality Stabilisation

Filter resistors are used in industrial and grid-connected systems to dampen harmonics and smooth voltage fluctuations, improving reliability and equipment longevity.
