Figure 2-122 Connection example for single-phase voltage transformer for 7SJ64 (phase-to-
ground voltages)
If phases of voltages V1 and V2 differ, phase displacement may be adjusted in
address 6122 ANGLE ADJUSTM..
The directional functionality and the displacement voltage element of this function
cannot be applied since there is no displacement voltage. Current elements of this
function, however, can be operated in non-directional mode
Except for the above-mentioned restriction the functional logic, scope of settings and
information are described in Section 2.12.
If the device is connected to only one voltage transformer, this function is set to inac-
tive and hidden.
Voltage-measuring monitoring functions such as "Voltage symmetry" and "Fuse-
Failure-Monitor" cannot be applied. They are set inactive and are hidden.
Several operational measured values cannot be calculated. If whole groups of opera-
tional measured values are concerned, they will be hidden. If only parts of a group are
concerned, corresponding operational measured values are set invalid (values are re-
placed by dashes) or reset.
