FP5000 Protection Features
• Three phase and ground overcurrent (50P-1,
50P-2, 50P-3, 51P and 50R-1, 50R-2,50R-3,51R,
50X-1,50X-2,50X-3,51X)
– Measured (X) and calculated (R) ground currents
• Negative sequence overcurrent (46-1, 46-2)
• Three phase over and under voltage protection
(27M-1, 59M-1, 27M-2, 59M-2)
• Single phase over and under voltage protection
(27A-1, 27A-2, 59A-1, 59A-2)
• Over and under frequency protection (81U-1,
81U-2, 81O-1, 81O-2)
FP5000 Protection Features
• Negative sequence over voltage
protection (47-1,47-2)
• Breaker failure (50BF)
– Internal Breaker Failure Initiation
– External Breaker failure Initiation
• Apparent and Displacement Power
factor (55A,55D)
• Four setting groups available
FP5000 Protection Features
• Zone Interlocking
– Faster fault clearing times with better zone
coordination
– Stuck breaker (breaker failure) accelerated
remote fault clearing
– Phase and ground selectable
– Extended range up to 1000’
– Works with DT3000
FP5000 Protection Features
•Zone Interlocking
•Fault @ Location 2
•Relay @ CB2 sees fault & sends
interlocking signal to upstream devices
at CB1
•Upstream devices continues to operate
on normal set time for remote backup
protection
•CB2 fast trips to interrupt fault
•If CB2 fails to interrupt fault in 10
cycles remote clearing of CB1 occurs
•Fault @ Location 1
•Relay @ CB2 does not see the fault no signal is sent to relay @ CB1
•Relay @ CB1 sees fault but does not
receive interlocking signal - Fast Trips
