Step
~
Set a number of phase to be detected for Undervoltage.
1P : More than 1 phase is detected with more than pickup voltage.
2P : More than 2 phases are detected with more than pickup voltage.
3P : More than 3 phases are detected with more than pickup voltage.
2) UNDER VOLT2 Setup
The undervoltage 2 settings process a very similar method to the undervoltage 1.
8.5.2.2. Overvoltage (59) and Neutral Overvoltage (64N)
In case that nominal voltage is kept higher than a certain voltage for a certain time, over voltage
elements makes an alarm operation. Over voltage elements is set in GROUP setting. Phase
overvoltage(59) elements are available to select a number of phase to be checked for overvoltage
function. Neutral overvoltage elements operate with zero sequence voltage (3V0) by the input
phase voltage. And negative Sequence overvoltage elements (V2) also operate by the input phase
voltage.
1) OVER VOLT1 Setup
The overvoltage 1 should be enabled to following settings.
GROUP # / MONITORING / VOLTAGE / OVER VOLT1 / Function

DISABLE, ENABLE
Default
DISABLE
Step
~
Set the function of over voltage 1 element as enable or disable.
If function = DISABLE, the feature is not operational.
If function = ENABLE, the feature is operational. When the feature
asserts an alarm condition, the device gives the alarm.
