Phase under-voltage protection (UV)
The under-voltage protection function for phase-to-earth (UV) consists of two stages (elements)
independently: UV1 and UV2. The time characteristic of the UV element is configured either
definite time (DT) or inverse definite minimum time (IDMT) using settings.
Each UV stage (element) detects the under-voltage condition of phase-to-earth. The user
can set a threshold and the ratio of a drip-out voltage (DO) to a pick-up voltage (PU) in the UV
element. To simplify the description, only the UV1 element is described, but the expression is
applicable to the UV2; hence, read the expression for the UV1 element as the UV2 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
