A basic need to permit planning of new ac power lines near railroad systems is accurate data for the levels of ac interference that upset the operation of railroad signal components or systems. Such data would help the power system and railroad system design engineer understand magnitude of the interference problem, investigate alternative mitigation approaches, and select one that is cost-effective and mutually agreeable. Under EPRI research program RP 1902-1, IITRI developed a body of key railroad signal equipment susceptibility data in cooperation with the major U.S. manufacturers of this equipment. This paper describes the innovative test jig developed under RP 1902-1 which has been applied to obtain susceptibility data for track and line relays, electronic track circuits, and grade-crossing warning devices. A companion paper (Part II) describes the results of the tests.
