THE PROGRAM
THE WORKSHOP
Few topics generate as much controversy and
argument as that of grounding and the associated
topics of surge protection, shielding and lightning
protection of electrical and electronic systems.
Poor grounding practice can be the cause of
continual and intermittent difficult-to-diagnose
problems in a facility. This workshop looks at
these issues from a fresh yet practical perspective
and enables you to reduce expensive downtime
on your plant and equipment to a minimum by
correct application of these principles.

INTRODUCTION AND BASICS
SURGE PROTECTION OF
ELECTRONIC EQUIPMENT
This workshop is designed to demystify the
subject of grounding and presents the subject in a
clear, straightforward manner. Installation,
testing and inspection procedures for industrial
and commercial power systems will be examined
in detail. Essentially this workshop is broken
down into grounding, shielding and surge
protection for both power and electronics
systems. Grounding and surge protection for
telecommunications and IT systems are
examined in detail. Finally, the impact of
lightning is examined and simple techniques for
minimising its impact are described.

PRE-REQUISITES
Some working knowledge of basic electrical
engineering principles is required, although there
will be a revision at the beginning of the
workshop. Experience with grounding problems
will enable the workshop to be placed in context.
