Summary of a Guide for Determining the Maximum Electric Power Station Ground Potential Rise and Induced Voltage from a Power Fault

Difficulties are experienced by telecommunication and protective relay engineers in determining the maximum power station ground potential rise, and/or induced voltages. Suitably rated protective devices are required for personnel safety and for the protection and continuity of service of wire line telecommunication facilities entering electrical power stations, or otherwise exposed to the influence of electrical power circuits. This is a summary of the IEEE Standards Ccmmittee Project No. P 367 proposed Guide which provides guidance for the calculation of these maximum voltages and for the acceptance of values lower than maximum, as well as the time requirements of coumunication channels where protective relaying is involved. The proposed Guide was submitted to the IEEE Standards Board by G. Y. R. Allen, Chairman of the PSOC Wire Line Subcommittee of PES and Chairman of the Inductive Coordination and Electrical Protection Subcommittee (Transmission Systems Committee) of the Cc mnunications Society.
