The L60 contains one auxiliary overvoltage element for each VT bank. This element is intended for monitoring overvoltage
conditions of the auxiliary voltage. The nominal secondary voltage of the auxiliary voltage channel entered under
SYSTEM
SETUP Ö AC INPUTS ØÖ VOLTAGE BANK X5 ØÖ AUXILIARY VT X5 SECONDARY is the per-unit (pu) base used when setting the
pickup level.
A typical application for this element is monitoring the zero-sequence voltage (3V_0) supplied from an open-corner-delta
VT connection.
