hai,
i want measure the three phase voltage without neutral wire. other way says three wire , three phase voltage measurement.
i was derived the 5 volts from three phase. i also done detect zero cross and phase seqence detection. but i need to measure phase to phase voltage.
present i done,measure the each phase and add two phase voltages. but it not accurately reading microntroller.
can any body suggest circuit, it will help tome.
