Current Phase-Rotation Supervision

8.3.8
8.3.8.1

Overview of Functions

The Current phase-rotation supervision function monitors the phase sequence of the secondary-circuit
currents by monitoring the sequence of the zero crossings (with same sign) of the currents. This enables the
device to detect connections that were inverted during commissioning. The criterion for the check is the
setting of the Phase sequence parameter.
The current measurement is based on the RMS values of the fundamental component.
8.3.8.2

Structure of the Function

The Current phase-rotation supervision function is located in the Power-system data of each 3-phase
current measurement point.
