IEEE Std. 998 – DIRECT LIGHTNING STROKE SHIELDING OF SUBSTATIONS
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
