IEC 63497 Ed. 1.0 en:2026

Full Description

IEC 63497:2026 This document, 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
