It gives compatibility levels for public medium voltage a.c. distribution systems having a nominal voltage between 1 kV and 35 kV and a nominal frequency of 50 Hz or 60 Hz (see IEC 60038). <\/p>\n<p><\/p>\n<p>Compatibility levels are specified for electromagnetic disturbances of the types which can be expected in public medium voltage power supply systems, for guidance in:<\/p>\n<p><\/p>\n<p>a) the limits to be set for disturbance emission into public power supply systems (including the planning levels defined in 3.1.5) <\/p>\n<p><\/p>\n<p>b) the immunity limits to be set by product committees and others for the equipment exposed to the conducted disturbances present in public power supply systems. <\/p>\n<p><\/p>\n<p>The disturbance phenomena considered are: <\/p>\n<p><\/p>\n<ul>\n<li>voltage fluctuations and flicker <\/li>\n<\/ul>\n<p><\/p>\n<ul>\n<li>harmonics up to and including order 50 <\/li>\n<\/ul>\n<p><\/p>\n<ul>\n<li>inter-harmonics up to the 50th harmonic <\/li>\n<\/ul>\n<p><\/p>\n<ul>\n<li>voltage distortions at higher frequencies (above 50th harmonic) <\/li>\n<\/ul>\n<p><\/p>\n<ul>\n<li>voltage dips and short supply interruptions<\/li>\n<\/ul>\n<p><\/p>\n<ul>\n<li>voltage unbalance<\/li>\n<\/ul>\n<p><\/p>\n<ul>\n<li>transient overvoltages<\/li>\n<\/ul>\n<p><\/p>\n<ul>\n<li>power frequency variation<\/li>\n<\/ul>\n<p><\/p>\n<ul>\n<li>d.c. components<\/li>\n<\/ul>\n<p><\/p>\n<ul>\n<li>mains signalling. <\/li>\n<\/ul>\n<p><\/p>\n<p>Most of these phenomena are described in IEC 61000-2-1.
