BS EN 61000 is a series on Electromagnetic compatibility (EMC). The goal of Electromagnetic compatibility is the correct operation of different equipment in a common electromagnetic environment. It is also the name given to the associated branch of electrical engineering. BS EN 61000-4-19 relates to the immunity requirements and test methods for electrical and electronic equipment to be conducted, differential mode disturbances and signalling in the range 2 kHz up to 150 kHz at a.c. power ports.
The object of BS EN 61000-4-19 is to establish a common and reproducible basis for testing electrical and electronic equipment with the application of differential mode disturbances and signalling to a.c. power ports. BS EN 61000-4-19 defines:
BS EN 61000-4-19 on electromagnetic compatibility is useful for:
Electromagnetic compatibility is the ability of electrical equipment and systems to function acceptably in their electromagnetic environment, by limiting the unintentional generation, propagation and reception of electromagnetic energy which may cause unwanted effects such as electromagnetic interference (EMI) or even physical damage in operational equipment. BS EN 61000-4-19 describes the tests that are intended to demonstrate the immunity of electrical and electronic equipment operating at a mains supply voltage up to 280 V (from phase to neutral or phase to earth, if no neutral is used) and a frequency of 50 Hz or 60 Hz when subjected to conducted, differential mode disturbances such as those originating from power electronics and power line communication systems (PLC).
The immunity to harmonics and inter-harmonics, including mains signalling, on a.c. power ports up to 2 kHz in differential mode are covered by IEC 61000-4-13. Emissions in the frequency range 2 kHz to 150 kHz often have both differential mode and common mode components. BS EN 61000-4-19 provides immunity tests only for differential mode disturbances and signalling. It is recommended to perform common mode tests as well, which are covered by IEC 61000-4-16. Conducted, differential mode disturbances and signalling in the frequency range 2 kHz up to 150 kHz may influence the performance of equipment and systems installed in all electromagnetic environments. Therefore, in this frequency range, differential mode disturbances and signalling are to be considered. As coupling of these disturbances and signalling could be very strong for a.c. power ports but is only relatively weak for all the other ports, the requirements of this standard apply to a.c. power ports only. Using BS EN 61000-4-19 you can understand the immunity requirements and test methods for electrical and electronic equipment to be conducted, differential mode disturbances and signal in the range 2 kHz up to 150 kHz at a.c. power ports.
