The operating time is completely independent of the measured neutral voltage, such that should
the neutral voltage exceed the set value during the same amount of time or more than the set
one during operation time, the protection function acts (trips) and there it is not restored until the
measured value of the neutral voltage drops below the voltage set point during adjusting reset
time.
The function pick up occurs at 100% of the adjusted input and the dropout at 95%. The reset
type is temporized and reset time is adjusted with reset time parameter.
The accuracy of the Time delay is equal to the preset time ±30 ms or ±0.5%
