Active Power Quality

Active harmonic filter
for 220V to 690V

GRIDSINE-G is the active harmonic filter of the Standard Series. It uses the same 3-level IGBT module as GRIDVAR-G, with a control card and firmware set up for harmonic filtering only, on 220V to 690V industrial systems.

Modules are rated 15 A to 200 A at 400V. With ≥98% filtering effectiveness, THDi at the point of common coupling drops below 5%, which meets IEEE 519 and IEC 61000-3-4 requirements.

Filtering covers the 2nd to 50th harmonic, with priority selection per order. This targets the orders that VFDs, UPS systems and rectifiers actually produce.

Key Features

2nd to 50th harmonic, 200 A modules, 20 in parallel

2nd–50th Harmonic Filtering

Filtering range 2nd to 50th harmonic. Each order can be selected and prioritised on its own, so capacity goes to the orders present in the load.

≥98% Filtering Effectiveness

Filtering effectiveness ≥98% at rated capacity. THDi at the PCC falls below 5%.

220V to 690V Operation

Operating voltage 220V, 400V, 480V or 690V. Native 690V modules for heavy industrial plants.

Up to 200A per Module

Nine module sizes from 15 A to 200 A at 400V. A larger module means fewer parallel units in a large installation.

3-Phase Load Balancing

Active negative-sequence compensation corrects the phase imbalance caused by single-phase non-linear loads.

Same Hardware, AHF Firmware

Identical physical module to GRIDVAR-G SVG. The difference is the control card and firmware, which run harmonic filtering only.

Module Variants

Nine 400V module sizes, 15 A to 200 A

15, 25, 30, 50, 75, 100, 125, 150 and 200 A at 400V. Up to 20 modules in parallel.

Applications

Applications: mixed drive loads and 4-wire networks

Four cases where per-order priority or the 4-wire neutral rating decides the choice.

VFD-Heavy Plants

Variable frequency drives are the main source of 5th, 7th, 11th and 13th harmonics. GRIDSINE-G targets these orders with individual priority selection.

Printing & Packaging

High-speed servo drives and DC motor controllers produce a broad harmonic spectrum. The 2nd to 50th range covers it.

Automotive

Welding robots, paint line rectifiers and conveyor VFDs each produce a different harmonic signature. Each order gets its own priority.

Commercial Buildings

LED lighting, IT equipment and HVAC drives raise neutral current and transformer heating. In 3P4W connection the neutral current rating is 3× rated current.

Need tighter space, higher cabinet capacity or broader harmonic filtering (2nd–51st)? Compare GRIDSINE-G with the Compact and SiC tiers.
