Description

The Line Voltage Sensor (Three-Phase) unit is an ideal three-phase line voltage sensor. The unit measures the line voltages of a three-phase network and outputs three signals. Each element of the output signals is proportional to the voltage between the phases:

  • Element 1:

  • Element 2:

  • Element 3:

Where:

, and are the voltages of phases a, b and c with respect to earth.

The Line Voltage Sensor (Three-Phase) unit is connected in parallel in the circuit.
