FREJA Win 5.3
FREJA Win is a graphical interface for the FREJA 306 Relay Testing System.
In FREJA Win, the all-round General instrument program serves as a convenient, easy to understand, user-friendly toolbox.
On the Connect page, you can enter information about how to connect the relay, including pictures if so desired.
On the Sequence page, you can vary all generator parameters independently. You can have up to 25 different states (prefault, fault1, prefault, fault2, prefault, fault3 etc.). This is useful when testing autoreclose relays or motor protection. It’s also possible to generate up to the 25th harmonic.
On the Ramp page, you can ramp all generator parameters independently. Amplitudes and angles are shown on a vector diagram, and values can be set using the knob on FREJA or the PC keyboard and mouse, on-line as well.
