Course Overview
Lightning is a common and significant cause of outages on most power systems. Mitigation of
the effects of lightning is often not well understood and can often be improved. This seminar is
designed to provide a background in lightning protection for those people responsible for the
reliability of power distribution and transmission systems as well as substations. The seminar
places great emphasis on assisting attendees with an understanding of the key principles
and concepts regarding lightning protection of power systems. The seminar will also
include constant references to international best practice, as articulated in the relevant Standards,
e.g., IEEE 1243, IEEE 1410, IEEE 998 and AS/NZ 1768.
Who should attend?
This 2-day seminar will present a practical approach to lightning protection and is intended for
managers and engineers concerned with the design of new lines and substations and with
implementing appropriate measures to improve the lightning performance of existing lines and
substations. It will be of considerable value to engineers and technicians involved in the operation
of power systems during thunderstorms. The seminar will also be of interest to non-specialist
engineers and graduate students who would benefit from an introduction to lightning and
lightning protection. No prior knowledge is assumed.
Participants may be required to work illustrative examples during the seminar and therefore should
bring a scientific calculator to the seminar.
About the Course Leader
Dr Franco D’Alessandro received the degrees of B.App.Sc. (majoring in
mathematics and physics), B.Ed. (secondary teaching) and Ph.D.(experimental
physics) from the University of Tasmania, Australia, in 1986, 1987 and 1996
respectively.
The first decade of his career was in university teaching & research. He then
moved into the private sector where he worked for more than a decade in
lightning protection and earthing as a senior research scientist and R&D product
engineer, both in Australia and the United States.
In December 2007, he established and managed PhysElec Solutions Pty Ltd, an independent
consultancy services company specialising in lightning protection and earthing as well as some
related aspects of high voltage engineering.
In June 2013, PhysElec Solutions Pty Ltd merged
with LPI Pty Ltd, continuing to provide standalone consulting services but with the new
capability to provide full turnkey solutions in lightning protection and earthing.
Dr D’Alessandro has delivered many seminars and presentations on lightning protection and
earthing within Australia and overseas and has published more than 80 technical papers. He is a
Senior Member of the IEEE and a participating technical member of Standards and code-setting
committees in Australia, Europe and the United States.
