Specifies electromagnetic compatibility (EMC) requirements for adjustable speed a.c.or d.c. motor drives connected to mains supplies up to 1000 volt a.c. Defines limits and test methods. Drives in traction applications are not covered. This Standard is technically identical to, and has been reproduced from, IEC 61800-3:1996.

This International Standard specifies electromagnetic compatibility (EMC) requirements for power drive systems (PDSs). These are adjustable speed a.c. or d.c. motor drives. Requirements are stated for PDSs which are connected to mains supplies with a rated voltage of up to 1 000 V a.c. r.m.s. For supply voltages higher than 1 000 V a.c. r.m.s. EMC requirements are under consideration and, until a new publication is produced, they will result from agreement between manufacturer/supplier and user.PDSs covered by this standard are those installed in industrial and residential environments with the exception of traction applications and electric vehicles. PDSs may be connected to either industrial or public power distribution networks. Industrial networks are supplied by a dedicated distribution transformer, which is usually adjacent to or inside the industrial location, and supplies only industrial customers. On the other hand, PDSs can be directly connected to low-voltage public mains networks which also supply domestic premises, and in which the neutral is generally earthed (grounded).PDSs covered by this standard are often included in a larger system, the system aspect is not covered by this standard, but guidance is provided in the informative annexes.The requirements have been selected so as to ensure an adequate level of electromagnetic compatibility (EMC) for PDSs in industrial and public locations. The levels cannot, however, cover extreme cases which are most unlikely to occur. Changes in the EMC behaviour of a PDS, as a result of fault conditions, are not taken into account.The object of this standard is to define the limits and test methods for a PDS. It includes immunity requirements and requirements against electromagnetic emissions. Emission can cause interference in other electronic equipment (for example radio receivers, measuring and computing devices). Immunity is required to protect the equipment from continuous and transient conducted and radiated disturbances, including electrostatic discharges. For evident economic reasons, the emission and immunity requirements should be balanced against each other and against the actual environment of the PDS.This standard defines the minimum electromagnetic compatibility requirements for a PDS.This standard does not specify all safety requirements for the equipment, such as protection against electric shocks, insulation co-ordination and related dielectric tests, unsafe operation, or unsafe consequences of a failure.In special cases, when highly susceptible apparatus is being used in proximity, additional mitigation measures may have to be employed to reduce the electromagnetic emission further below the specified levels, or to increase the immunity of the highly susceptible apparatus.This product EMC standard for PDSs takes precedence over all aspects of the generic standards, and no additional EMC tests are required or necessary. If a PDS is included as part of equipment covered by a separate EMC product standard, the EMC standard of the complete equipment applies.
