IEC 62586-1 Ed. 2.0 b:2017

Power quality measurement in power supply systems - Part 1: Power quality instruments (PQI)

IEC 62586-1:2017 specifies product and performance requirements for instruments whose functions include measuring, recording and possibly monitoring power quality parameters in power supply systems, and whose measuring methods (class A or class S) are defined in IEC 61000-4-30.
 These requirements are applicable in single, dual- (split phase) and 3-phase AC power supply systems at 50 Hz or 60 Hz.
 This edition includes the following significant technical changes with respect to the previous edition:
 a) integration of the new measurement functions of IEC 61000-4-30:2015 (e.g. RVC and current functions);
 b) integration of the new requirements of IEC/TS 61000-6-5:2015, update of definitions of environment G and H, update of applicable EMC performance criteria;
 c) correction of minor mistakes, improvement in specification.
 It has the status of a basic EMC publication in accordance with IEC Guide 107.
