CURRENT
The metered current values display for all line terminals in fundamental phasor form. All angles are shown with respect to
the reference common for all L30 devices; that is, frequency, source currents, and voltages. The metered primary
differential and restraint currents display for the local relay.
Terminal 1 refers to the communication channel 1 interface to a remote L30 at terminal 1. Terminal 2 refers to the
communication channel 2 interface to a remote L30 at terminal 2.
