The 469 Motor Management Relay was designed to display lagging angles.
Therefore, if a system condition would cause the current to lead the voltage by 45°,
the 469 relay will display such angle as 315° Lag instead of 45° Lead.
When the currents and voltages measured by the relay are zero, the angles
displayed by the relay and those shown by the EnerVista 469 Setup
software are not fixed values.
The EnerVista 469 Setup software is a useful tool to view the vectors seen by the
relay in graphical format. The same information described above is displayed by the
EnerVista 469 Setup software as follows:
