VT pri Nominal voltage of the Voltage
Transformers at the primary side. The phase
to phase voltage is to be entered even if the
load is in delta connection.

VT sec Nominal voltage of the Voltage
Transformers at the secondary side. The
phase to phase voltage is to be entered
even if the load is in delta connection.

taken into account in the direct
measurement of the residual voltage (GVT

delta phi -
Mode
The delta phi element (vector surge) trips, if
the permissable voltage angle shift (delta
phi) of the three measured voltages (phase-
ground or phase-phase) in: one phase, two
phases or within all phases is exceeded.
