the scheme switch.

When [VCHK] is set to "SYN", three-phase autoreclose is performed only with the synchronism
check.

When [VCHK] is set to "OFF", three-phase autoreclose is performed without the voltage and
synchronism check.

The voltage and synchronism check requires a single-phase reference voltage from the busbar or
line. If three-phase voltages used by the current differential protection are supplied from the line
voltage transformer, the reference voltage will need to be supplied from the busbar voltage
transformer. On the contrary, if three-phase voltages used by the current differential protection
are supplied from the busbar voltage transformer, the reference voltage will need to be supplied
from the line voltage transformer.

Additionally, it is not necessary to fix the phase of the reference voltage.

To match the busbar voltage and line voltage for the voltage and synchronism check option
described above, the GRL100 has the following three switches as shown in Figure 2.15.2.4:

[VTPSEL]:

This switch is used to match the voltage phases. If the A-phase voltage or
A-phase to B-phase voltage is used as a reference voltage, "A" is selected.

[VT-RATE]: This switch is used to match the magnitude and phase angle. "PH/G" is

selected when the reference voltage is a single-phase voltage while
"PH/PH" is selected when it is a phase-to-phase voltage.

[3PH-VT]:

"Bus" is selected when the three-phase voltages are busbar voltages while
"Line" is selected when they are line voltages.
