This screen shows all the protection element blocks available. Protection elements block
signals can be configured at Setpoint > Relay Configuration > Protection Elements.
Protection status signals (pickups and operations) for time overcurrent, instantaneous
overcurrent and directional protection functions for phase current.
Protection status signals (pickups and operations) for time overcurrent, instantaneous
overcurrent and directional protection functions for neutral current (calculated from
phases).
Protection status signals (pickups and operations) for time overcurrent, instantaneous
overcurrent and directional protection functions for ground current (measured from 4
current input).
Protection status signals (pickups and operations) for time overcurrent, instantaneous
overcurrent, isolated and directional protection functions for ground current (measured
th
from 5 current input).
Protection status signals (pickups and operations) for negative sequence time overcurrent
function.
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.
Protection status signals (pickups and operations) for all voltage functions, undervoltage,
overvoltage, neutral overvoltage, negative sequence overvoltage and auxiliary under and
over voltage.
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).
Status signals (pickups and operations) for under, overfrequency and frequency rate of
change units.
Status signals for synchrocheck function (25).
Status signals for autoreclose function (79). Close signal, recloser status (ready, lockout,
etc.), block signals after each shot.
Status signals for breaker failure function (50BF).
Fuse failure detection signal.
Status signals (pickups and operations) for broken conductor (I2/I1).
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.
Status signals (pickups and operations) for locked rotor units.
Status signals for pulse counters units.
Status signals for analog comparator units.
Status signals (pickups and operations) for load encroachment units.
Status signal for number of starts operations
Status signals for the Digital Counter units.
Status signals for the Cold Load Pickup Function.
