A continuous casting and rolling mill operating 14 transformers across two voltage levels. High reactive demand from arc furnaces and rolling drives was causing heavy utility penalty charges and voltage instability at the MV bus. Forte deployed custom-engineered GRIDFIX panels per transformer, each fitted with CSM100 thyristor modules for stepless reactive power tracking.

A large-scale rolling mill complex with three distinct voltage levels supplying melting, rolling and auxiliary loads across 14 transformers. Distorted current waveforms were causing overheating in transformer windings and nuisance tripping of sensitive drives. Forte carried out a full site power quality survey and designed bus-level GRIDFIX compensation matched to each transformer's load profile.

A clinker production facility operating large VFD-driven kiln and mill motors generating significant harmonic distortion across the 400V distribution network. Reactive power fluctuations were causing voltage sag events during motor starts. Forte engineered and supplied a GRIDVAR-C SVG panel solution providing continuous reactive power compensation and active harmonic filtering on the most critical busbars.

An electric arc furnace steel plant with highly non-linear and rapidly fluctuating loads generating severe harmonic content and reactive power swings on the 690V network. Standard IGBT-based SVG systems could not track the load dynamics fast enough. Forte specified the GRIDVAR-X SiC module — with its 4µs response and 25.6 kHz switching frequency — to achieve real-time harmonic cancellation across the 2nd–51st orders.
