Verification Tests of the VEPCO 500-kY System

The results of the first field tests performed to verify the design of the Virginia Electric Power Company 500-kV system are presented. Initial radio influence measurements made on each line section are compared with levels calculated during the design studies. Switching-surge voltages recorded during various normal and abnormal switching conditions are given, and are shown to be well within predicted values. Descriptions are given of the measuring equipment and techniques used for the field tests and for a continual monitoring of the system.
