Neutral Current - GE c60 Instruction Manual

CHAPTER 5: SETTINGS
The phase instantaneous overcurrent element can 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
Instantaneous Overcurrent (IOC) Element Response to Saturated Waveforms in UR Series Relays (GET-8400A).
