Functionality
The three-phase overvoltage protection function PHPTOV is applied on power
system elements, such as generators, transformers, motors and power lines, to protect
the system from excessive voltages that could damage the insulation and cause
insulation breakdown. The three-phase overvoltage function includes a settable value
for the detection of overvoltage either in a single phase, two phases or three phases.
PHPTOV includes both definite time (DT) and inverse definite minimum time
(IDMT) characteristics for the delay of the trip.
The function contains a blocking functionality. It is possible to block function outputs,
timer or the function itself, if desired.
