This seminar, provided by CPD International, will present a practical approach to lightning protection to electricity substations and overhead lines. It 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.
