Quick guide Coupling Device VG1200
1 Application and short description
In order to achieve higher efficiencies and to reduce line losses, inverters with a higher output voltage than the usual
3AC 400 V are often used in large on-site generation systems.
So that the grid and system protection can monitor this high voltage, it must be reduced. This is usually done with voltage
converters. With the VG1200 coupling device, an ohmic voltage divider is available that takes on this task. In conjunction
with the VG1200 coupling device, the UFR1002IP can measure voltages of up to 1200 V. The display in the UFR1002IP
is scalable. This means that the voltages at the input of the VG1200 are displayed and the limits for protection against
over- and undervoltage are set accordingly. Both devices together meet the requirements of VDE-AR-N 4110 (feeding
into the medium-voltage grid).
