Whether you work with hydro, wind, thermal, or alternative power generation; power generators; low voltage or high voltage distribution; power distribution racks or cables; smart grid or ensuring workplace safety, the power industry has a strong focus on standardization and interoperability. This list on EMC (Electromagnetic Compatibility) includes standards from ISO and others.
IEC 61000-2-4:2024 is available as IEC 61000-2-4:2024 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition. IEC 61000-2-4:2024 is related to conducted disturbances in the frequency range from 0 kHz to 150 kHz. It gives compatibility levels in differential mode (L-L and L-N) for industrial locations, with a nominal voltage up to 35 kV and a nominal frequency of 50 Hz or 60 Hz. NOTE 1 Industrial locations are defined in 3.1.8. Power distribution systems on ships, aircraft, offshore platforms and railways are not included. NOTE 2 See also Annex E. The compatibility levels specified in this document apply at the in-plant point of coupling (IPC). The level of the low-frequency disturbances at the terminals of equipment receiving its supply from the IPC is generally assumed to be similar to the disturbance level at the IPC itself. However, in some situations this is not the case, particularly when a long feeder is dedicated to the supply of a particular load, or when a disturbance is generated or amplified within the installation of which the equipment forms a part. Compatibility levels are specified for the types of low-frequency electromagnetic disturbances expected at any in-plant point of coupling (IPC) within industrial locations, for guidance in the definition of: a) limits for disturbance emissions in industrial power distribution systems (including the planning levels defined in 3.1.5); NOTE 3 A very wide range of conditions is possible in the electromagnetic environments of industrial networks. These are approximated in this document by the three classes described in Clause 4. However, it is the responsibility of the operator of such a network to take account of the particular electromagnetic and economic conditions, including equipment characteristics, in setting the above-mentioned limits. b) immunity levels for the equipment within these systems. The disturbance phenomena considered are: - voltage deviations; - voltage dips and short interruptions; - voltage imbalance; - power-frequency variations; - harmonics up to order 40; - interharmonics up to the 40th harmonic; - voltage components above the 40th harmonic up to 150 kHz; - DC component; - transient overvoltages. The compatibility levels are given for different classes of environment determined by the characteristics of the supply network and loads. NOTE 4 Compatibility levels at the point of common coupling (PCC) on public networks are specified in IEC 61000 2 2 for low-voltage networks and IEC 61000 2 12 for medium-voltage networks. IEC TR 61000 3 6 and IEC TR 61000 3 7 describe the approach of power distribution system operators to the limitation of emissions from installations and large loads. This third edition cancels and replaces the second edition published in 2002. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) introduction of new classes 2a, 2b and 2L (former class 2); b) modification of existing compatibility levels for class 3; c) addition of compatibility levels in the frequency range 2 kHz to 150 kHz; d) addition of compatibility levels using a new quantity: partial weighted harmonic distortion (PWHD).
IEC 61000-6-1:2016 for EMC immunity requirements applies to electrical and electronic equipment intended for use in residential, commercial, public and light-industrial locations. Immunity requirements in the frequency range 0 Hz to 400 GHz are covered. No tests need to be performed at frequencies where no requirements are specified. This generic EMC immunity standard is applicable if no relevant dedicated product or product-family EMC immunity standard exists. This third edition cancels and replaces the second edition published in 2005. This edition constitutes a technical revision.
"IEC 61000-6-3:2006+A1:2010 This part of IEC 61000 for EMC emission requirements applies to electrical and electronic apparatus intended for use in residential, commercial and light-industrial environments. Emission requirements in the frequency range 0 Hz to 400 GHz are covered. No measurement needs to be performed at frequencies where no requirement is specified. This generic EMC emission standard is applicable if no relevant dedicated product or product-family EMC emission standard exists. This standard applies to apparatus intended to be directly connected to a low-voltage public mains network or connected to a dedicated DC source, which is intended to interface between the apparatus and the low-voltage public mains network. This standard applies also to apparatus which is battery operated or is powered by a non-public, but non-industrial, low-voltage power distribution system if this apparatus is intended to be used in the locations described below. The environments encompassed by this standard are residential, commercial and light-industrial locations, both indoor and outdoor. The following list, although not comprehensive, gives an indication of locations that are included: - residential properties, for example houses, apartments; - retail outlets, for example shops, supermarkets; - business premises, for example offices, banks; - areas of public entertainment, for example cinemas, public bars, dance halls; - outdoor locations, for example petrol stations, car parks, amusement and sports centres; - light-industrial locations, for example workshops, laboratories, service centres. Locations that are characterised by being supplied directly at low voltage from the public mains network are considered to be residential, commercial or light-industrial. The object of this standard is to define the emission test requirements for apparatus defined in the scope in relation to continuous and transient, conducted and radiated disturbances. The emission requirements have been selected so as to ensure that disturbances generated by apparatus operating normally in residential, commercial and light-industrial locations do not exceed a level which could prevent other apparatus from operating as intended. Fault conditions of apparatus are not taken into account. Not all disturbance phenomena have been included for testing purposes in this standard but only those considered as relevant for the equipment covered by this standard. These requirements represent essential electromagnetic compatibility emission requirements. Requirements are specified for each port considered. This consolidated version consists of the second edition (2006) and its amendment 1 (2010). Therefore, no need to order amendment in addition to this publication. "
This part of IEC 61000 sets high-altitude electromagnetic pulse (HEMP) immunity requirements for electrical and electronic equipment intended for use indoors. The indoor HEMP environment depends on the electromagnetic shielding quality of a facility and the level of protection against the conducted environment. This standard is intended for all facility types including residential, commercial, light industrial, hospitals, heavy industrial, power substations and power generation facilities. This standard includes indoor equipment intended to be connected to a low-voltage (1 kV or less) power network, to the telecom network and/or to external antennas. Immunity test values are based on the 90 % severity levels in IEC 61000-4-25. All telecom lines are assumed to have gas-tube protectors at the point where they enter the building and insulation flashover on low-voltage lines are assumed at three times that of lightning. For signal ports connected to internal cables, severity test levels are based on cables that have a total length of 10 m and a procedure is provided for longer cables. This part of IEC 61000 does not specify safety requirements for equipment, such as protection against shock, insulation coordination, and related dielectric tests. Nevertheless, the immunity tests described in this part of IEC 61000 involve hazardous voltages. High-voltage precautions are necessary to protect the health and safety of test personnel.
