VE-Protection Module – Residual Voltage [59N]
VE-Protection Module – Residual Voltage [59N]
Available stages:
VE[1] ,VE[2]
Both elements of the residual voltage supervision
VE[1]
and
VE[2]
are
identically structured.
The residual voltage can be measured in via the auxiliary winding da-dn (e-n) (broken delta).
The residual voltage can be calculated only if the phase voltages (star connection) are connected to the
measuring inputs of the device.
