New framework for utility power quality (PQ) data analysis

Power quality monitoring of many sites of a utility produces an enormous amount of data. The analysis of this data can take place in many different ways at many different levels. This paper provides a conceptual framework for describing the data analysis process. It can be represented graphically in the form of a triangle with data flow from the bottom upwards and enables consistency in PQ analysis and helps identify where there are deficiencies in present analysis practices
