This window shows the phasors for voltage and current values, phase to phase, phase to ground and sequence values,
provided by the unit. The angles provided by the unit are clockwise, all the angles are positive values, so for a system Va
(0,0°), Vb (0,-120°), Vc (0,120°) the relay will provided the following angles Va (0,0°), Vb (0,120°), Vc (0,240°).
