Modeling guidelines for fast front transients

This paper summarizes the works of an IEEE Task Force focused on development of modeling guidelines for fast front transients (i.e., frequency range from 10 kHz up to 1 Ma). These guidelines are intended to be used by engineers involved in digital simulations of electro-magnetic transients, with particular emphasis on lightning surge analysis of overhead lines and substations. Modeling philosophies, simplified mathematical relationships, typical data, and examples are given for various power system components. To illustrate the overall modeling procedure, a case study has been presented.
