4. 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 trending or data logger feature is used to sample and record up to eight actual
values at an interval defined by the user. Several parameters can be trended and
graphed at sampling periods ranging from 1 second up to 1 hour. The parameters
which can be trended by the EnerVista 469 Setup software are:
• Currents/Voltages:
Phase Currents A, B, and C, and Average Phase Current
Motor Load
Current Unbalance
Ground Current
Differential Currents A, B, and C
System Frequency
Voltages Vab, Vbc, Vca Van, Vbn & Vcn
• Power:
Power Factor
Real (kW or hp) Reactive (kvar), and Apparent (kVA) Power
Positive Watthours
Positive and Negative Varhours
Torque
