DIN EN 61000-2-4 VDE 0839-2-4:2003-05

This standard contains the German version of the European Standard EN 61000-2.4:2002 and is identical with the the International Standard IEC 61000-2-4. It specifies compatibility levels for low-frequency conducted disturbances and signalling in industrial and other non-public power supply systems for the frequency range 0 Hz to 9 kHz. The following phenomena are considered: voltage deviations voltage unbalance, voltage dips and short interruptions of the supply voltage, harmonics, interharmonics, voltage distortions at frequencies above the 50th harmonic, transient overvoltages, temporary power frequency variations and d.c. components.
