GridClass®-Mod is a flexible, standardized modular system concept that combines various filtering, damping, and compensation technologies to achieve comprehensive improvement of grid power quality – from base-load operation to the suppression of high-frequency disturbances.

The modules can be used individually or in combination and cover a wide range of functions, from classic reactive-power compensation to the elimination of complex resonance conditions.

Functional highlights:

• Broadband filtering: Effective against harmonics, supraharmonics, and grid resonances.

• Modular architecture: Each module can be easily integrated, expanded, or replaced – ideal for switchgear builders and system integrators.

• Innovative technology mix: Includes

  • SOFIA®-mod – intelligent filter modules,

  • RESI-mod – resonance elimination systems,

  • SIMΩN® – active damping and dynamic reactive current compensation,

  • CLASSIC-mod – proven classical compensation technology.

• Plug-and-play integration: Standardized modules enable fast project planning, installation, and commissioning.

GridClass®-Mod is a future-proof solution for modern networks increasingly affected by non-linear loads, converter-based equipment, and decentralized energy production.
