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.
CURRENT LEVEL
Displays the value
and angle of the
current phasor
