Description of BS EN IEC 63497:2026 2026IEC 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.
