Specifications

Advanced Power Control and Monitoring
Two Power Managers, one
each dedicated to utility and
onsite power sources, provide
protective relay functions for
reliable parallel operation of the
sources. The power managers
include digital inputs and out-
puts (Device 86).
In addition to directional
power, a directional overcur-
rent device provides the most
reliable protection against
undesirable backfeeding of
onsite power to the utility grid.

systems. This component:
• Actively controls engine
generator output voltage
and speed to synchronize
the onsite power source with
utility power (Device 25)
• Includes analog and PWM
(pulse width modulated) out-
puts for controlling engine
speed/loading and analog
output for generator voltage/

• Includes communication
ports that provide Internet
and intranet access for
status checks and remote
control
• Records and displays
a time-and-date-stamped
log of all system events
and alarms (including those
caused by protective trip
functions)
• Includes a GUI
(graphical user interface)
for system set up,
monitoring, and control
