Metering Devices, Protective Relays, Software and Connectivity
Protective Relays
Features, Benefits and Functions
●
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 LEDs and
logic control features that
can replace and eliminate
external auxiliary relays,
timers, light 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 (viewable using
PowerNet and
NPWAVEFORM
component
●
Front RS-232 port and
PowerPort software
provides local computer
access and a user-friendly,
Windows-based interface
for relay settings, and
configuration and data
retrieval
●
Drawout case design
for quick and easy relay
removal and replacement
●
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-6000 for
relay settings, monitoring
and control
The protection functions are
listed below and shown on
Page V3-T9-168.
The FP-6000 provides phase
overcurrent (forward, reverse
or both):
●
Two-stage instantaneous
with timers (50P-1 and
50P-2)
●
Inverse time overcurrent
(51P)
●
Directional control (67P)
●
10 standard curves
●
Instantaneous or time
delay reset
●
Voltage restrained inverse
time overcurrent (51P2)
The FP-6000 provides two
ground overcurrent elements,
one measured (IX) and one
calculated (IR):
●
Independent measured
ground or neutral
directional overcurrent
elements:
●
Two-stage
instantaneous with
timers (50X-1 and 50X-2)
●
Inverse time overcurrent
(51X)
●
Ground directional
polarizing (67N) -3vo and
negative sequence
●
10 standard curves
●
Instantaneous or time
delay reset
●
Independent calculated
ground or neutral
directional overcurrent
elements:
●
Two-stage
instantaneous with
timers (50R-1 and
50R-2)
●
Inverse time overcurrent
(51R)
●
Ground directional
polarizing (67N) –3vo,
I pol and negative
sequence
●
10 standard curves
●
Instantaneous or time
delay reset
The FP-6000 also provides
the following protective
features:
●
Breaker failure (50BF)
●
Phase unbalance negative
sequence overcurrent
(46-1, 46-2)
●
Phase voltage unbalance
and sequence protection
(47-1, 47-2)
●
