Digitrip 3000 Curve Shape Possibilities
In addition to being able to provide a circuit breaker
“OPEN” or “CLOSED” status to the remote location, the
Digitrip 3000 displays and remotely transmits parame-
ters, such as:
• Individual phase currents
• Ground current
• Maximum current for each phase and ground since last
reset (Amp. Demand)
• Magnitude and phase of current causing trip
• Cause of trip
• Current transformer ratio
• Existing setpoint settings
• Software Version
The remote communications capability is made possible
by the Cutler-Hammer Integrated Communications
(INCOM) Chip and Protocol compatible with the Power-
Net Monitor and Control System. The protocol permits a
remote master computer to perform:
(1) Interrogation of relay data
(2) Execution of circuit breaker “Close” and “Trip”
commands
(3) “Reset” of the relay after a trip
(4) Downloading of settings
Reliable two-way communications can be provided over a
twisted pair communications network. The Digitrip 3000
Protective Relay is supplied with a built-in communica-
tions capability compatible with the Cutler-Hammer Pow-
erNet system.
