Passive Power Quality Systems

Modular compensation panels and high-performance components engineered for demanding industrial environments. From 12.5 kVAr 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. Built around a unique drawer-type architecture, every stage of the system is an independent hot-swappable module — allowing maintenance and expansion without production downtime.

Designed for the harshest electrical environments — iron & steel, mining, cement, petrochemical — GRIDFIX complies with IEC 61439-2 Form 4B, the highest safety classification for low-voltage switchgear.

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

GRIDFIX Advantages

The New Standard in Dynamic Compensation

In heavy industrial environments, standard compensation is never enough. GRIDFIX handles high dynamic loads, mitigates harmonics, and corrects power factor simultaneously with millisecond precision.

Ultra-Fast Response

Thyristor-based switching in ≤10ms. Zero transient effects on sensitive equipment.

Hot-Swap Modularity

Replace any module without stopping the system. 95% reduction in production downtime.

Maximum Safety

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

High ROI

Eliminates reactive power penalties. Extends equipment life. Short payback period.
