Overvoltages on the AEP 765-kV System

Abstract

Overvoltages on the American Electric Power 765-kV transmission system and their influence on its design are studied. Overvoltage phenomena are defined and described during the transient, dynamic, and steady-state periods. The effect of these periods on equipment and means for their control are discussed. Examples of data important in arriving at final system design are given. Analytical tools used during the overvoltage studies are discussed and areas requiring further research are listed.
