Power reference unit is used to provide the external DC signal, on which the acts. It can be used as a power reference in application where a generator is operated in parallel with the grid. The operator simply sets the desired capacity that should be provided by the generator and adjusts the generator speed to transfer load to or from the grid.
Power remote systems consist of a transmitter and receiver unit that transmits power and sensor information through an air gap. It can connect to inductive, capacitive, optical, magnetic or mechanical sensors. It connects up to 15-signal transmission.
