Answer Posted / sethuraman.v
we can measure the voltage through multimeter (i.e)in multimeter having only two probs. so we can measure only 2phases (i.e)440V to measure the 3 phase voltage we have to use the formulae of 3 phase power (root3 VI COSO)by applying this formula we can calculated as 440V
