Non-directional overcurrent protection (OC)
Overcurrent protection relay (hereafter referred to as OC) detects overcurrent conditions and
operates accordingly. In each CH, the OC function has two stages (OC1 and OC2 elements),
which operate independently. To simplify the description, only OC1 element is discussed but is
applicable to OC2; hence, read the expression for OC1 as OC2 for the OC2 stage unless a
special explanation or instruction has been provided.

Note: The implementation of particular features is dependent upon the selection of
hardware and the configuration of functions. Several IED models do not support certain
features. To determine whether a particular feature has been implemented within an IED,
identify the IED ordering number; and check the order number for the "G&T position" whilst
referring to the comparison table below. For more information, see Appendix: Ordering.
