Passive Power Quality Systems

Modular compensation panels and their components. 12.5 kvar steps to 500 kvar per cabinet, 400V to 750V.

Flagship Product

GRIDFIX
Modular Compensation Series

The GRIDFIX Series is Forte's own-IP modular passive compensation system. Each stage is an independent drawer module that can be hot-swapped, so maintenance and expansion do not stop production.

GRIDFIX is designed to IEC 61439-2 Form 4B for iron and steel, mining, cement and petrochemical plants.

IEC 61439-2 Form 4B ≤10ms Response Hot-Swap Modules 400V–750V Up to 500 kvar/Cabinet cosφ ≥ 0.99

GRIDFIX Advantages

Thyristor switching, hot-swap drawers, Form 4B separation

GRIDFIX switches steps in ≤10 ms, filters harmonics with detuned reactors and corrects power factor to cosφ ≥ 0.99.

≤10 ms Response

Thyristor-based switching in ≤10 ms.

Hot-Swap Modularity

Replace any module without stopping the system.

Form 4B Separation

IEC 61439-2 Form 4B. Isolated busbars. Safe intervention under live power.
