IEEE 487-2015 - IEEE Standard for the Electrical Protection of Communications Facilities Serving Electric Supply Locations -- General Considerations

Standard Details

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.

Existing Standards	Active IEEE 367-2012 - IEEE Recommended Practice for Determining the Electric Power Station Ground Potential Rise and Induced Voltage from a Power Fault Guidance for the calculation of power station ground potential rise (GPR) and longitudinal induction (LI) voltages is provided, as well as guidance for their appropriate reduction from worst-case values, for use in metallic telecommunication protection design.
	Superseded IEEE 1137-1991/Cor 1-2009 - IEEE Guide for the Implementation of Inductive Coordination Mitigation Techniques and Applications--Corrigendum 1 IEEE Std 1137-1991 provides guidance for controlling or modifying the inductive environment and the susceptibility of affected wire line telecommunications facilities in order to operate within the acceptable levels of steady-state or surge induced voltages of the environmental interface (probe wire) defined by IEEE Std 776-1987. Procedures for determining the source of the problem are given. Mitigation theory and philosophy are discussed, and mitigation devices are described. The application of typical mitigation apparatus is addressed. Advice for determining the best engineering solution is offered, and general safety considerations are discussed. This corrigendum corrects Table 3?Longitudinal Balance Performance Thresholds and the first and last sentences of the third paragraph in 8.5 of IEEE Std 1137-1991.
	Active IEEE 487.1-2014 - IEEE Standard for the Electrical Protection of Communication Facilities Serving Electric Supply Locations Through the Use of On-Grid Isolation Equipment Workable methods for protecting wire-line telecommunication circuits entering electric supply locations are presented. The electric supply location environment; protection apparatus; service types, reliability, service performance objective classifications, and transmission considerations; protection theory and philosophy; protection configurations; installation and inspection; and safety are covered in this document.
	Active IEEE 776-2018 - IEEE Recommended Practice for Inductive Coordination of Electric Supply and Communication Lines The inductive environment that exists in the vicinity of electric power and wire-line telecommunications systems and the interfering effects that may be produced are addressed. An interface that permits either party, without need to involve the other, to verify the induction at the interface by use of a probe wire is presented. This recommended practice does not apply to railway signal circuits.
