Protection Blocks
This screen shows all the protection element blocks available. Protection
elements block signals can be configured at "Setpoint>Relay
Configuration > Protection Elements".
Phase Current
Protection status signals (pickups and operations) for time overcurrent,
instantaneous overcurrent and directional protection functions for phase
current.
Neutral Current
Protection status signals (pickups and operations) for time overcurrent,
instantaneous overcurrent and directional protection functions for neutral
current (calculated from phases).
Ground Current
Protection status signals (pickups and operations) for time overcurrent,
instantaneous overcurrent and directional protection functions for ground
current (measured from 4
Sensitive Ground
Protection status signals (pickups and operations) for time overcurrent,
Current
instantaneous overcurrent, isolated and directional protection functions
for ground current (measured from 5
Negative Sequence
Protection status signals (pickups and operations) for negative sequence
Current
time overcurrent function.
Voltage
Protection status signals (pickups and operations) for all voltage
functions, undervoltage, overvoltage, neutral overvoltage, negative
sequence overvoltage and auxiliary under and over voltage, Volts/Hz and
ground overvoltage.
Power
Protection status signals (pickups and operations) for all power units .
Frequency
Status signals (pickups and operations) for under, overfrequency and
frequency rate of change units.
Synchrocheck
Status signals for synchrocheck function (25).
Breaker Failure
Status signals for breaker failure function (50BF). Enhanced models only.
VT Fuse Failure
Fuse failure detection signal. Enhanced models only.
Setting Groups
Status signals (activations and blocks) for the relay setting group change.
By default the "setting group" setting is disabled and all the grouped
elements can be enabled at the same time.
Pulse Counters
Status signals for pulse counters units.
Analog Comparator
Status signals for analog comparator units.
Loss of Mains
Status signals (operations) for loss of mains (78V). Enhanced models
only.
Loss of excitation
Status signals (pickups and operations) for loss of excitation (40).
Accidental
Status signals (off-line, armed and operation) for inadvertent generator
Energization
