V unbal
, which is calculated as maximum difference between two phase voltages.
The protection activates if the voltage unbalance gets over the threshold for time
longer than
N
OTE
:
The voltage unbalance protection is created in the default archive using the
mechanism of
universal analog protections
. That means
this setpoint is one of
general-purpose setpoints
, which may be used for different purpose if the
protection is deleted from the configuration.

Description
This setpoint adjusts the delay for the generator voltage unbalance protection.
The threshold for the protection is adjusted by setpoint
