Metering Devices, Protective Relays, Software and Connectivity
Protective Relays
Features, Benefits and Functions
When the FP-4000 isn’t
responding to disturbances
in the power system, it’s
providing valuable metering
information at the relay and
remotely. It provides energy
usage and demand reading,
and can alarm when usage
reaches a set value. Power
factor measurements can be
used for cap bank switching
to control kVAR demand.
Onboard data trending can
provide load profiles for up
to 40 days.
●
Complete protection,
metering and control in a
single compact case to
reduce panel space, wiring
and costs
●
Flexible current, voltage
and frequency protection
and programmability to
cover a broad range of
applications while
simplifying relay ordering
and reducing inventory
●
Integral test function
reduces maintenance time
and expense
●
Relay self-diagnostics and
reporting improves uptime
and troubleshooting
●
Breaker trip circuit
monitoring improves the
reliability of the breaker
operation
●
Programmable logic control
features that can replace
and eliminate external
auxiliary relays, timers
and wiring
●
Zone selective interlocking
improves coordination and
tripping times and saves
money compared to a
traditional bus differential
scheme
●
Trip and event recording
in non-volatile memory
provides detailed
information for analysis
and system restoration
●
256 cycles of waveform
capture aids in post fault
analysis
●
Front RS-232 port and
PowerPort software
provides local computer
access and a user-friendly,
WindowsT-based interface
for relay settings, and
configuration and data
retrieval
●
Breaker open/close control
from relay faceplate or
remotely via
communications
●
Remote communications
to Eaton PowerNet
monitoring system or PC
●
Free PowerPort utility
software for local PC
interface to the FP-4000 for
relay settings, monitoring
and control
The protection functions are
listed below and shown on
Page V3-T9-185.
Phase Overcurrent
●
Two-stage instantaneous
with timers (50P-1 and
50P-2)
●
Inverse time overcurrent
(51P-1)
●
10 standard curves
●
Instantaneous or time
delay reset
●
Two independent
directional overcurrent
elements, one measured
(IX) and one calculated (IR)
●
Two-stage
instantaneous with
timers (50X-1 and 50X-2)
(50R-1 and 50R-2)
●
Inverse time overcurrent
(51X and 51R)
●
10 standard curves
●
Instantaneous or time
delay reset
●
Breaker failure (50BF)
●
Phase unbalance negative
sequence overcurrent
(46-1, 46-2)
●
Phase voltage unbalance
and sequence protection
(47-1, 47-2)
●
Main three-phase under/
overvoltage (27M-1,
27M-2, 59M-1, 59M-2)
●
Auxiliary single-phase
under/overvoltage (27A-1,
27A-2, 59A-1, 59A-2)
●
Under/overfrequency
(81U-1, 81U-2, 81O-1,
81O-2)
●
Power factor (55)
●
Zone interlocking for bus
protection (87B). The
FP-4000 feeder relay
includes a zone selective
interlocking feature that
can be used with other
Eaton devices like the
Digitrip 3000 overcurrent
relay
