VOLTAGE ELEMENTS
AUXILIARY UV1
The D30 contains one auxiliary undervoltage element for each VT bank. This element is intended for monitoring undervolt-
age conditions of the auxiliary voltage. The
AUX UV1 PICKUP
selects the voltage level at which the time undervoltage ele-
ment starts timing. The nominal secondary voltage of the auxiliary voltage channel entered under

VOLTAGE BANK X5
AUXILIARY VT X5 SECONDARY
is the per-unit base used when setting the
pickup level.
The
AUX UV1 DELAY
setting selects the minimum operating time of the auxiliary undervoltage element. Both
AUX UV1 PICKUP
and
AUX UV1 DELAY
settings establish the operating curve of the undervoltage element. The auxiliary undervoltage element
can be programmed to use either definite time delay or inverse time delay characteristics. The operating characteristics
and equations for both definite and inverse time delay are as for the phase undervoltage element.
The element resets instantaneously. The minimum voltage setting selects the operating voltage below which the element is
blocked.
