IEC TR 61850-90-17:2017

Communication networks and systems for power utility automation - Part 90-17: Using IEC 61850 to transmit power quality data

IEC TR 61850-90-17:2017(en) provides a way of exchanging power quality data between instruments whose functions include measuring, recording and possibly monitoring power quality phenomena in power supply systems, and clients using them in a way that is compliant to the concepts of IEC 61850. The main goal is the interoperability of power quality instruments. This document provides::
- Guidelines for using of IEC 61850 for power quality domain;
- Name space extensions based on power quality function assessment;
- Profile for using IEC 61850 in the specific context of IEC 61000-4-30.
