Relays: Recording on F-PRO

In addition to the protection functions, F-PRO provides transient fault recording to facilitate analysis of the power system after a disturbance has taken place. The triggers for transient fault recording are established by the user programming the output matrix & allowing any internal relay function or any external input to initiate recording.
