Refer to chapter 9:
Application of settings
for the calculation examples for the phase comparison element.
In single phase comparison schemes, coincidence of the local and remote squares is detected during half the power cycle
only, positive or negative. As a result, some delay in operation can be expected under
unfavorable
fault inception. This
weakness of the single phase comparison schemes is eliminated in dual phase comparison schemes but cost of the com-
munication link is higher.
