Map Phasor Sets
Range: Show Graph, Phasor Set 1, Phasor Set 2, Phasor Set 3,..., Phasor Set 12
Default: <Empty>
This option selects the phasor sets to display on each of the six available phasor graphs.
The "Show Graph" option must be selected for each of the six graphs to display the
specified phasors. Single or multiple phasor sets can be displayed on each graph as per
user preferences.

The EnerVista UR Setup software groups the D90
primary functions. Each function has its own setting parameters and each generates its
own outputs in the form of operands.
• Communications.
• Protection.
• Automation.
• Digital fault recorder (DFR).
• Metering.
• Equipment manager.
• Self-tests.
• Front panel interface (HMI).
However, it is often desirable for an output from an element within one function can be
available to an element within another function. For instance, it may be useful for the
digital fault recorder to record the output operands of any protection element.
Consequently a fixed, predetermined set of operands is available as to each function as
shown below.
