Introduction: Organised by the Energy Network Association (ENA), National Grid is in collaboration with DNO companies to conduct a system wide survey on the existing harmonic distortion on the electricity supply system in the UK The survey has been conducted since February 2005.

Objectives: The key objectives of this survey are as follows:

To determine the harmonic voltage levels during the defined 5 years
To obtain the trend of harmonic distortion for the period of survey
To investigate any correlation in harmonic voltages on transmission and distribution systems at the measured sites
Verify whether or not the existing control measures are sufficient to meet the needs of a society with an ever appetites for equipment that generates harmonic current.
