Overvoltage protection for phase-to-phase (OVS)
The over voltage protection function in phase-to-phase (OVS) detects an over voltage condition
that phase-to-neutral voltage is larger than a setting and operates accordingly. The OVS
function has two stages (elements; OVS1 and OVS2), which operate independently. The OVS
element has a time delay characteristic; and the user can select either (1) independent
(definite) time characteristic delay or (2) dependent (inverse) time characteristic delay. The
OVS element is configured both the setting of a pickup voltage (PU) and the setting of a drop-
off voltage (DO).
To simplify the description, only OVS1 is discussed, but the expression is applicable to
OVS2; hence, read the expression for OVS1 as the OVS2 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
