Voltage is nothing but potential difference, so we can take
only 2 objects if we want to measure the difference between
them. So we always measure this difference of potential
between 2 not 3.

A powerplant has 8 gensets operating in grid parallel mode. In one genset sometimes there is pf variation and kvar variation. The plant operates in pf mode. When this variation is observed the load is stable, voltage is also stable, freq and genset speed is also stable. How will you check the functioning of pf card. What shall be the ideal output vdc of the pfc, from there it is input to AVR?

We are planning to synchronized DG's with our captive plant in the event of black start of plant, but before sync we checked voltage of DG with our plant voltage and it varies from 5 V to 450 V. So in this condition how we can sync DG with plant ?
