what is phase to phase voltage? what is line to line voltage

Answer Posted / kella

--Star Circuit--

As for Phase Voltage = PVa to N
*which is always = 240V (on each phase)

As for Line Voltage = PVa to PVb
= 240 x 1.732 (square root of 3)
= 415V

*Line Voltage: The voltage present between any two of the
conductors in a three-phase system. It is 1.732 times higher
than phase voltage in a WYE connection.

*Phase Voltage: The voltage between any one conductor and
ground.

we have earthmat at 110KV substation.we would like to take earth resistance.b some says that by connecting earth megger terminals (C1,P1) at middile point of earthmat (at riser) will cause voltage gradient at other earthmat nods and dont get exat earth resistance.when connecting at end nods will get exat value . is it correct .please explain
