GROUPED ELEMENTS
This element is used to give a time-delay operating characteristic versus the applied fundamental voltage (phase-to-
ground or phase-to-phase for wye VT connection, or phase-to-phase for delta VT connection) or as a definite time element.
The element resets instantaneously if the applied voltage exceeds the dropout voltage. The delay setting selects the
minimum operating time of the phase undervoltage. The minimum voltage setting selects the operating voltage below
which the element is blocked (a setting of "0" allows a dead source to be considered a fault condition).
