Cost-effective Folding transformer for the installation of a subsequent transformer measurement
Measurement of high primary currents, the transformer has a small secondary current Current output, which can then be connected to measuring devices, e.g. UMG 96.
If the If the measuring device needs to be replaced, the load does not need to be switched off switched off, as the measuring device is not directly connected to the supply line in the supply line. This prevents unplanned system downtimes.
Important: Operation of the current transformer in the upper third of the specified current.
