IEEE EMC-S PL reported activity no. 4/2023: EMC MARATHON at EMC EUROPE EMC "Electromagnetic Pulses"
The RS105 test method specified in MIL-STD-461F refers to the risk of radiated exposure to an Electromagnetic pulse (EMP) event. EMP could interfere with electronic systems located in the vicinity.
MIL-STD-461 RS105 refer to different variations of EMP. The main area of our activity is nuclear electromagnetic pulse (NEMP), which are magnetic fields caused by nuclear explosions.
NEMP test system mainly consists of a high voltage pulse generator connected to a transmission line. The system can be mounted indoor or outdoor. The following MIL-STD-461 RS105, the equipment under test (EUT) is exposed to an EMP. The system generates impulse which minimum amplitude of the field is 50 kV/m. The duration of the impulse is 23 ± 5 ns. The equipment under test is installed underneath the transmission line within the predetermined uniform field area. The generated electric and magnetic fields are monitored during testing. For proper standard testing, the equipment must be exposed to five pulses. The equipment cannot demonstrate of performance degradation or malfunction.
EMP susceptibility is increasingly measured in a number of industries and applications. This research deals with safety-critical equipment and subsystems, in particular on military equipment. MIL-STD-461 applies to different variations of EMP. The RS105 test method specified in MIL-STD-461F applies to the risk of radiated exposure to an EMP event. EMP could interfere with electronic systems located in the vicinity.
MIL-STD-461 RS105 is applicable to equipment and subsystem enclosures which are exposed to the external electromagnetic environment. Testing is applicable to equipment installed in exposed environments on ships, submarines, vehicles and aircraft.
In this work, the examinations using NEMP (Nuclear Electromagnetic Pulse) test system. In particular, the aim of the research was to verify the ability of the equipment enclosure to withstand a transient electromagnetic field.
The RS105 limit requires that the equipment shall not degradation of performance malfunction, or deviation from specified indications above the equipment's specific tolerances. The equipment must be exposed to five pulses.
The presented results of experimental show effects of electromagnetic pulse. We will present in detail counteract the negative effects of transient electromagnetic field.
