Guidance is provided for the calculation of interfering voltages and their appropriate reduction from worst-case values for use in wire-line telecommunication protection design. Information is also included for the determination of the fault current and earth-return current levels; their probability, waveform, and duration; and the impedance to remote earthing points used in these ground potential rise (GPR) and longitudinally induced voltage calculations. The zone of influence of the power station GPR; the calculation of the inducing currents; the mutual impedance between power and wire-line telecommunication facilities and shield factors; and the channel time requirements for wire-line telecommunication facilities where noninterruptible channels are required for protective relaying and other purposes are covered.

Other Activities From This Working Group
Current projects that have been authorized by the IEEE SA Standards Board to develop a standard.
No Active Projects
Standards approved by the IEEE SA Standards Board that are within the 10-year lifecycle.
No Active Standards
These standards have been replaced with a revised version of the standard, or by a compilation of the original active standard and all its existing amendments, corrigenda, and errata.
No Superseded Standards
These standards have been removed from active status through a ballot where the standard is made inactive as a consensus decision of a balloting group.
No Inactive-Withdrawn Standards
These standards are removed from active status through an administrative process for standards that have not undergone a revision process within 10 years.
No Inactive-Reserved Standards
