The phase instantaneous overcurrent element may be used as an instantaneous element with no intentional delay or as a
definite time element. The input current is the fundamental phasor magnitude. For timing curves, see the publication Instan-
taneous Overcurrent Element Response to Saturated Waveforms in UR-Series Relays (
GET-8400A ).
