Answer Posted / hiren bhatt
in star connection line voltage of system is decreased to 1
by square root of 3 is equal to 1/1.73 of line voltage,
thats why in starting motor get reduced voltage asper this
ratio and hence star connection help to reduce effect of
dv/dt to the connected load and hence its insulation and
starting current protected

at work we have a 3 phase motor but on testing one phase isnt getting a reading. it runs 24 hours a day all week. stops and starts well no noise or heating. the phase isnt down to earth.is it just a bad meter reading or not? phases one and three came up with a resistance reading of 0.4 but phase 2 couldnt get anything shows up as open circuit.
