IEEE Std. 998 – DIRECT LIGHTNING STROKE SHIELDING OF SUBSTATIONS

Share

Overview:

This 4-hour tutorial will provide a review of the recently released IEEE Std. 998 guide. Empirical and EGM shielding methods for direct lightning stroke interception (including the newly added Eriksson EGM) will be reviewed and examples presented in step-by-step detail. The basic principles behind four alternative models for direct lightning stroke interception will be presented and discussed with a practical example.

Tutorial Outline:

  • Overview of changes between 1996 and 2012 version
  • Lightning characteristics
  • Lightning exposure and substation risk assessment
  • Review of traditional methods with examples: fixed angle and empirical curves
  • Review of basic electrogeometric model with examples: rolling sphere method
  • Review of the improved EGM with examples
  • Description of four alternative models for substation shielding: LPM, CVM, LIT and SLIM
  • Example shielding designs with the four alternative models
  • Conclusions
  • Q & A

Biography:

Franco D’Alessandro holds the degree of B.App.Sc., B.Ed. and PhD. He also holds GAICD, MIEAust and SMIEEE.

The first decade of his career was in university teaching and research. 

In 1997, he moved into the private sector and worked on many aspects of lightning protection and earthing from research to products and applications, both in Australia and the United States. In 2007, he set up PhysElec Solutions Pty Ltd, providing independent consultancy services on lightning protection and earthing projects for a wide range of clients globally.

In 2003, PhysElec solutions merged with Lightning Protection International Pty Ltd, where it continues to provide independent consultancy services in lightning protection and earthing. Dr. D'Alessandro is currently Chief Technology Officer at LPI.

Franco has delivered many seminars and presentations on lightning protection and earthing in Australia and overseas and has published more than 100 technical papers. Apart from engineering institution membership, he has been an active contributor to Standards and code-setting committees in Australia (AS/NZ 1768), Europe (TC81, IEC 62305,IEC 62561) and the USA (IEEE998) for almost 20 years.
