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

Answer Posted / mayambela

there is no phase to phase in star connection
only you find Phase to Phase in delta connection because line voltage equal to phase voltage

DELTA CONNECTION
VRY IS PHASE TO PHASE OR LINE TO LINE voltage (only in delta)
VYB S PHASE TO PHASE OR LINE TO LINE voltage(only in delta)
VBR IS PHASE TO PHASE OR LINE TO LINE voltage (only in delta)

STAR CONNECTION
Vrn is phase voltage
Vyn is phase voltage
Vbn is phase voltage

VRY is line to line voltage
VYB is line to line voltage
VBR is line to line voltage
