6.2.4.1 Frequency
F650 units incorporate three overfrequency and three underfrequency units. For each of them there are two magnitudes
pickup and trip (operation).
Frequency elements are often used in generating plants, as well as in the connection of substations to the main system.
Frequency monitoring is the base for synchronous machines protection application, with a couple of setting levels, as well
as for the development of automatic shedding functions and underfrequency reset.
This screen shows the activation of all frequency elements available in the F650. It can be accessed from the menu:
