Current practice and future challenges for power quality monitoring - CIGRE WG C4.112 perspective

This paper describes the initial activities of the recently created CIGRE WG C4.112 “Guidelines for Power quality monitoring - measurement locations, processing and presentation of data”. The WG was created in January 2011 in recognition of demand for coherent set of guidelines for power quality monitoring in existing and future power networks to meet increasing customers' and the regulatory agencies' demands to provide information on the actual power quality level in power networks. Though still at early stages of the work the members of the WG compiled an extensive material about the state of the art of power quality monitoring. This paper summarizes current understanding of power quality monitoring issues and points out directions in which the WG will continue to work over next couple of years in order to provide answers to outstanding questions.
