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.
This recommended practice addresses the *inductive environment* that exists in the vicinity of electric power and wire-line telecommunications systems and the interfering effect that may be produced thereby; guidance is offered for the control or modification of the environment and the susceptibility of the affected systems in order to maintain an acceptable level of interference.
An acceptable level is defined as an amount of steady-state or surge induced longitudinal voltage or current that does not cause a personnel or public safety hazard, damage to cable or equipment, and/or circuit degradation or failure.
To aid the user of this recommended practice in calculating induction between power and telecommunication lines, the concept of an interface is developed. This recommended practice permits either party, without need to involve the other, to verify the induction at the interface by use of a probe wire.
This recommended practice does not apply to railway signal circuits.
