These voltage transformers are used in the following applications:

  • in IT grids without neutral conductor
  • in applications in which the grid voltage is too high for the measuring inputs

The voltage transformer consists of a three phase input and three phase output with additional neutral.
Using these transformers, even the measurement devices of the series UMG 96… can be used in IT grids. Furthermore, it can be used for all metering instruments, when the grid voltage ist too high for the measuring inputs.
