Protection
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
th
current input).
Sensitive Ground
Current
Protection status signals (pickups and operations) for time overcurrent, instantaneous
overcurrent, isolated and directional protection functions for ground current (measured
from 5
th
current input).
Negative Sequence
Current
Protection status signals (pickups and operations) for negative sequence time overcurrent
function.
Thermal Model
Protection status signals for thermal model. Reset, alarm and operation signals for phases
and for unit, besides the thermal image values in percentage for all phases and units.
Voltage
Protection status signals (pickups and operations) for all voltage functions, undervoltage,
overvoltage, neutral overvoltage, negative sequence overvoltage and auxiliary under and
over voltage.
Power
Protection status signals (pickups and operations) for forward, directional and wattmetric
ground fault (high and low) power units, and power factor status. Power values for 32N
High and Low functions (in watts).
Control Elements
Frequency
Status signals (pickups and operations) for under, overfrequency and frequency rate of
change units.
Synchrocheck
Status signals for synchrocheck function (25).
Autoreclose
Status signals for autoreclose function (79). Close signal, recloser status (ready, lockout,
etc.), block signals after each shot.
Breaker Failure
Status signals for breaker failure function (50BF).
VT Fuse Failure
Fuse failure detection signal.
Broken Conductor
Status signals (pickups and operations) for broken conductor (I2/I1).
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.
Locked Rotor
Status signals (pickups and operations) for locked rotor units.
Pulse Counters
Status signals for pulse counters units.
Analog Comparator
Status signals for analog comparator units.
Load Encroachment
Status signals (pickups and operations) for load encroachment units.
Max. Number of Starts
Status signal for number of starts operations
Digital Counters
Status signals for the Digital Counter units.
Cold Load Pickup
Status signals for the Cold Load Pickup Function.
