EMI Impact to wayside

Modern passenger transit rail vehicles are equipped with a large number of microprocessor based/controlled subsystems that are susceptible to electromagnetic interference (EMI). Wayside mounted control systems are also easily affected by EMI generated from electrically powered vehicles high voltage subsystems, such as traction motors, static inverters, etc.

Standard: MIL-STD-461 - Requirements for the Control of Electromagnetic Interference Characteristics of Subsystems and Equipment Purpose: This standard establishes interface and associated verification requirements for the control of the electromagnetic interference (emission and susceptibility) characteristics of electronic, electrical, and electromechanical equipment and subsystems. There is a variety of equipment types and applications within this document, additional details should be provided when specifying. Criteria: Specify compliance with standard, with details Usage: Shall meet the requirements of MIL-STD-461, (add details)

Standard: MIL-STD-462 - Test Method Standard For Measurement Of Electromagnetic Interference Characteristics Purpose: This standard contains general test methods necessary to demonstrate compliance of subsystems and equipment to the requirements of MIL-STD-461 Criteria: Specify compliance with standard, meeting criteria of the test(s) required in MIL-STD-461 Usage: Shall meet the requirements of MIL-STD-462, (add details)
