The turbo regulator regulates the machine set to the nominal speed. Consequently, the station's own
demands can be continuously supplied at nominal frequency.
Since the dropout threshold is 20 MHz below or above the trip frequency, the resulting “minimum” trip
frequency is 30 MHz above or below the nominal frequency.
A frequency increase can, for example, occur due to a load shedding or malfunction of the speed regulation
(e.g. in a stand-alone system). In this way, the frequency protection can, for example, be used as overspeed
protection.
