Omfang

IEC 63497:2026, which is a product standard, is intended to specify the EMC, performance and safety requirements of shunt-connected active correction devices (ACD) with rated system voltages not exceeding 1 000 V AC or 1 500 V DC.These devices can be either cord or permanently connected. They can be movable, stationary, or fixed devices.An ACD includes both a static VAR generator (SVG) and an active harmonic filter (AHF).The primary function of a shunt connected ACD is to do one or more of the following:- active harmonic filtering;- reactive power compensation;- unbalanced load compensation.Additional functions of a shunt-connected ACD, not addressed by this document, can be the following:- flicker compensation;- interharmonic component filtering.In case of hybrid devices, combining a passive harmonic filter and an ACD, this document covers only the active part.This document does not cover- active mitigation functions part of another device (variable speed drive, uninterruptible power supply, dynamic voltage restorer, etc.),- switched power capacitors,- switched inductors,- passive harmonic filters,- energy storage converters, and- series-connected active correction devices.
