Description

The Line Voltage Sensor (Three-Phase) block represents an ideal three-phase line voltage sensor. The block measures the line-line voltages of a three-phase system and outputs a three-element physical signal vector. Each element of the physical signal output vector is proportional to the voltage between the phases as follows:

  • Element 1: Vab = Va - Vb

  • Element 2: Vbc = Vb - Vc

  • Element 3: Vca = Vc - Va

where Va, Vb, and Vc are the absolute a-, b-, and c-phase voltages.
