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.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.
