5.4.8.5 AUXILIARY UNDERVOLTAGE ELEMENT (27X)
This is an Auxiliary undervoltage element for general use that uses as its input magnitude the voltage measured by the 4
th
VT, terminals A11-A12.
Table 5–65: 27X ELEMENT SETTINGS
The snapshot event setting enables or disables the snapshot event generation for this element.
5.4.8.6 VOLTAGE UNBALANCE (60V)
This element controls the power system unbalance margin. It is based on the "Voltage Unbalance Factor" defined
according to IEC as:
Factor % = V2/V1
Table 5–66: VOLTAGE UNBALANCE SETTINGS
FUNCTION
Enables/disables function 60V.
PICKUP LEVEL
Element 60V pickup level. This setting is based on the system unbalance% according to the formula V2/
V1 in the measuring.
The V2 negative sequence or the positive sequence V1 value should be greater than
5 V
. The unit will not
work below this threshold.
TRIP DELAY
Element 60V trip delay. The equipment will work once the unbalance factor keeps its value above the trip
threshold during the time determined by this setting.
RESET DELAY
Once the unit has worked and the unbalance factor is below the 97% of the activation threshold, the
equipment will keep the trip until the reset time is over. Then the reset of the unit will take place.
EVENTS
Enables or disables the function event generation. All the status in the function are influenced by this
setting.
