Recommended Practice for Determining the Electric Power Station Ground Potential Rise and Induced Voltage from a Power Fault
This standard provides guidance for the calculation of power station ground potential rise (GPR) and longitudinally induced (LI) voltages and guidance for their appropriate reduction from worst-case values for use in metallic telecommunication protection design. Information is also included for the determination of the following: a) The fault current and the earth return current levels; their probability, waveform, and duration; and the impedance to remote earthing points used in these GPR and LI calculations as well as the effective X/R ratio. b) The zone of influence (ZOI) of the power station GPR. c) The calculation of the inducing currents, the mutual impedance between power and metallic telecommunication facilities, and shield factors. d) The channel time requirements for metallic telecommunication facilities where non-interruptible channels are required for protective relaying.

IEEE Standard for the Electrical Protection of Communications Facilities Serving Electric Supply Locations -- General Considerations
General considerations are presented for the electrical protection of telecommunications facilities serving electric supply locations. This standard contains material that is common to the IEEE 487(TM) family of standards (i.e., dot-series) including fundamental protection theory; basic electrical protection philosophy, concepts, and designs; protection apparatus; service types; reliability; service performance objective (SPO) classifications; and transmission considerations. In general, special protective measures, handling procedures, and administrative procedures are necessary to provide electrical protection against damage to telecommunications facilities and equipment, maintain reliability of service, and ensure the safety of personnel.
