Question 47 phase sequence

[Izeldeen]

Hi every body, who can help me here:
How would you go about testing a microprocessor relay with the 47 function that measures 120 volts phase to phase?
a- Single phase voltage multiplied by 1.73
b- 2 line-to-neutral voltages of 69 volts
c- 2 channels connected open Delta, one at O degrees, and the other at 60 degrees leading
d- 2 channels connected open Delta, one at O degrees, and the other at 120 degrees leading
