The metered current values are displayed for all line terminals in fundamental phasor form. All angles are shown with
respect to the reference common for all L90 devices; that is, frequency, source currents, and voltages. The metered pri-
mary differential and restraint currents are displayed for the local relay.
Terminal 1 refers to the communication channel 1 interface to a remote L90 at terminal 1. Terminal 2 refers
to the communication channel 2 interface to a remote L90 at terminal 2.
