    Abstract - (Show below) - (Hide below)

    Specifies electromagnetic compatibility (EMC) requirements for adjustable speed a.c. or d.c. motor drives connected to mains supplies up to 1000 V a.c. Defines limits and test methods. Drives in traction applications are not covered.

    Scope - (Show below) - (Hide below)

    This part of IEC 61800 specifies electromagnetic compatibility (EMC) requirements for powerdrive systems (PDSs). A PDS is defined in 3.1. These are adjustable speed a.c. or d.c. motordrives. Requirements are stated for PDSs with converter input and/or output voltages (line-to-line voltage), up to 35 kV a.c. r.m.s.PDSs covered by this standard are those installed in residential, commercial and industriallocations with the exception of traction applications, and electric vehicles. PDSs may beconnected to either industrial or public power distribution networks. Industrial networks aresupplied by a dedicated distribution transformer, which is usually adjacent to or inside theindustrial location, and supplies only industrial customers. Industrial networks can also besupplied by their own electric generating equipment. On the other hand, PDSs can be directlyconnected to low-voltage public mains networks which also supply domestic premises, and inwhich the neutral is generally earthed (grounded).The scope of this part of IEC 61800, related to EMC, includes a broad range of PDSs from afew hundred watts to hundreds of megawatts. PDSs are often included in a larger system. Thesystem aspect is not covered by this standard but guidance is provided in the informativeannexes.The requirements have been selected so as to ensure EMC for PDSs at residential,commercial and industrial locations. The requirements cannot, however, cover extreme caseswhich may occur with an extremely low probability. 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 according to itsintended use. This standard includes immunity requirements and requirements for electro-magneticemissions.NOTE 1 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. The emission and immunity requirements are balanced against each other and against the actual environment of the PDS.This standard defines the minimum EMC requirements for a PDS.Immunity requirements are given according to the environment classification. Low-frequencyemission requirements are given according to the nature of the supply network. High-frequencyemission requirements are given according to four categories of intended use, which cover both environment and bringing into operation.As a product standard, this standard may be used for the assessment of PDS. It may also be used for the assessment of CDM or BDM (see 3.1), which can be marketed separately.This standard contains:– conformity assessment requirements for products to be placed on the market;– recommended engineering practice (see 6.5) for cases where high frequency emissions cannot be measured before the equipment is placed on the market (such PDSs are defined in 3.2.6 as category C4).NOTE 2 The first edition of IEC 61800-3 identified that the intended use could require engineering for putting into service. This was done by the “restricted distribution mode”. Equipment that used to be covered by the “restricted distribution mode” is covered in the second edition by categories C2 and C4 (see 3.2).This standard is intended as a complete EMC product standard for the EMC conformityassessment of products of categories C1, C2 and C3, when placing them on the market (seedefinitions 3.2.3 to 3.2.5).Radio frequency emission of equipment of category C4 is only assessed when it is installed inits intended location. It is therefore treated as a fixed installation, for which this standardgives rules of engineering practice in 6.5 and annex E, although it gives no defined emissionlimits (except in case of complaint).This standard does not specify any safety requirements for the equipment such as protectionagainst electric shocks, insulation co-ordination and related dielectric tests, unsafe operation,or unsafe consequences of a failure. It also does not cover safety and functional safetyimplications of electromagnetic phenomena.In special cases, when highly susceptible apparatus is being used in proximity, additionalmitigation measures may have to be employed to reduce the electromagnetic emission furtherbelow the specified levels or additional countermeasures may have to be employed toincrease the immunity of the highly susceptible apparatus.As an EMC product standard for PDSs, this standard takes precedence over all aspects of thegeneric 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.
