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.
