AS IEC 61000.4.1:2017 pdf free.Electromagnetic compatibility (EMC) Part 4.1: Testing and measurement techniques- Overview of the IEC 61000-4 series.
EXAMPLE Examples of commercial, public or light-industrial locations are (see IEC TR 61000-2-5 for further information):
— retail outlets, for example shops, supermarkets;
— business premises, for example offices, banks, hotels, data centers;
— areas of public entertainment, for example cinemas. public bars, dance halls;
— places of worship, for example temples. churches, mosques, synagogues;
— outdoor locations, for example petrol stations, car parks, amusement and sports centers:
— general public locations, for example park, amusement facilities, public offices;
— hospitals, educational institutions, for example schools, universities, colleges;
— public traffic area, railway stations, and public areas of an airport;
— light-industrial locations, for example workshops, laboratories, service centers.
Note 1 to entry: The connection between location and electromagnetic environment is given in 3.1.
3.4
industrial location
location characterized by a separate power network, supplied from a high- or medium-voltage transformer, dedicated for the supply of the installation
EXAMPLE Examples of industrial locations are metalworking, pulp and paper, chemical plants. car production, farm building, high voltage (HV) areas of airports.
Note 1 to entry: Industrial locations can generally be described by the existence of an installation with one or more of the following characteristics:
— items of equipment installed and connected together and working simultaneously;
— significant amount of electrical power is generated, transmitted and/or consumed;
— frequent switching of heavy inductive or capacitive loads;
— high currents and associated magnetic fields;
— presence of industrial, high power scientific and medical (ISM) equipment (for example, welding macnines)
The electromagnetic environment at an industrial location is predominantly produced by the equipment and installation present at the location. There are types of industrial locations where some of the electromagnetic phenomena appear in a more severe degree than in other installations.
Note 2 to entry: Industrial locations can be further distinguished, for example into general. process, heavy or power industrial locations (see lEG TR 61000-2-5 for further information).
Note 3 to entry: The connection between location and electromagnetic environment is given in 3.1.AS IEC 61000.4.1 pdf download.
