How can system technical performance be specified, evaluated,

and improved by considering:

Item 1 - New techniques, tools and application experiencesrelated to electromagnetic compatibility, insulation coordination,

lightning protection, power quality and power system security;

Item 2 - System technical performance indices and their impact

on customers, asset owners and regulators;

Item 3 - The influence of environmental stresses (such as

lightning and pollution);

Item 4 - The interaction of electrical equipment and customer

installations with the power system(Over 120 participants at the peak and more than 60 constantly throughout the day)
