Function 59. Definite-time phase overvoltage
There are two independent phase overvoltage functions
This protection function is adjusted using four parameters:

The operating time is completely independent from the measured phase voltage, such that
if the phase voltage exceeds the adjusted value for a period of time equal to or higher than
the pre-established value, the protection function actuates (trips) and does not reset itself
until the measured phase voltage value drops below the pre-established voltage point
during adjusting reset time.
The function activates at 100% of the adjusted input and deactivates at 95%. Reset is
temporized and reset time is adjusted with reset time parameter.
The accuracy of the operating time is the adjusted time ±30ms or ± 0.5% (greater of both).

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 Operating 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 operating time is the adjusted time ±30ms or ± 0.5% (greater of both).
NOTE
: Depending on the configuration the neutral voltage can be measured or
calculated:
