2.2.7. Overvoltage protection (59)
The three-phase overvoltage protection comprises two stages,
U> and U>>, with separately adjustable operating times.
The function is based on measuring the fundamental frequency
component of the phase-to-phase voltages, of which the highest
value constantly is compared with the set start value of the
overvoltage protection.
