DIN EN 61000-2-12 VDE 0839-2-12:2004-01

This standard contains the German version of the European Standard EN 61000-2.12:2003 and is identical with the Internaitonal Standard IEC 61000-2-12:2003. It specifies compatibility levels for low-frequency conducted disturbances and signalling in public medium-voltage power supply systems for the frequency range 0 Hz to 9 kHz with an extension up to 148,5kHz for mains signalling. The following phenomena are considered: voltage fluctuations and flicker; harmonics, interharmonics, voltage distortions at frequencies above the 50th harmonic, voltage dips and short interruptions of the supply voltage, voltage unbalance, transient overvoltages, temporary power frequency variations, d.c. components and disturbances from the mains signalling
