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)
