Proceedings: Telephone lines entering power substations
- eds.
The EPRI workshop on ''Telephone Circuits Entering Substations'' was designed for technology interchange. It also served to evaluate the need for possible joint research by the telephone companies and the electric utilities related to requirements and methods for protection of telephone circuits entering power substations. Attendance at the meeting totalled 57, with a ratio of electric utility to telephone personnel about two to one. Papers were presented on typical applications and practices, modeling and measurement of ground potential rise, a review of the IEEE tutorial on substation grounding design practices, and new, available protective equipments. The ensuing discussions involved disagreements, in some cases, between measured ground potential differences and values derived by modeling. The application of probabilistic and risk analysis techniques, and new technology including semiconducting and non-linear devices for isolating or reducing overvoltages on telephone circuits resulting from ground faults, switching surges or lightning strikes were also included.
