The IEEE 1159 is a recommended guideline that provides the user with a consistent set of terms, definitions and practices for describing power quality phenomena.

The focus of this white paper is on IEEE 1159 definitions. Understanding these definitions is the first step in proper implementation of these guidelines which allows the operator to make useful measurements of PQ related phenomena.

This includes the appropriate techniques along with the monitoring location for a given measurement, enhancing the value of the data collected for useful analysis of power quality issues.
