2BGLOBAL SETTINGS
0BDEVICE CONFIGURATION
Location:
Identifier of the relay’s location.
Feeder Side:
Phase CT ratio:
Nominal turns-ratio of the instrument current transformer. This
ratio affects the current values reflected by the secondary at the relay and the
trip settings of the current protection functions.
Ground CT ratio:
Idem to the previous parameter but referenced to the neutral
current.
Phase PT ratio:
Nominal ratio of the instrument voltage transformer where the
relay is connected in feeder side. This ratio affects directly the voltage values
reflected by the secondary in the relay and the trip settings of several
protection functions.
Load Side:
Phase PT ratio:
Nominal ratio of the instrument voltage transformer where the
relay is connected in load side. This ratio affects directly the voltage values
reflected by the secondary in the relay and the trip settings of several
protection functions.
Voltage Wiring:
Can be selected between wye (4 wires), open delta (3 wires) or
phantom.
Default Active Settings Group:
Active settings group currently in use at the
relay. Six groups of different settings for the main protection functions can be
selected in this control. Each group has its own settings.
Phase Rotation:
Sequence of the analog input voltage. (ABC or ACB)
Frequency:
Frequency power system (60/50 Hz)
