SYNCHK1 V1 SOURCE:
This setting selects the source for voltage V1 (see NOTES below).
SYNCHK1 V2 SOURCE:
This setting selects the source for voltage V2, which must not be the same as used for the V1 (see NOTES below).
SYNCHK1 MAX VOLT DIFF:
This setting selects the maximum voltage difference in 'kV' between the two sources. A voltage magnitude difference
between the two input voltages below this value is within the permissible limit for synchronism.
SYNCHK1 MAX ANGLE DIFF:
This setting selects the maximum angular difference in degrees between the two sources. An angular difference between
the two input voltage phasors below this value is within the permissible limit for synchronism.
SYNCHK1 MAX FREQ DIFF:
This setting selects the maximum frequency difference in 'Hz' between the two sources. A frequency difference between
the two input voltage systems below this value is within the permissible limit for synchronism.
