in star connection we have get neutral point but in delta we have not got neutral point

Answer / kamal gulati

in star connection,
LINE VOLTAGE = 1.732 PHASE VOLTAGE
LINE CURRENT = PHASE CURRENT

in delta connection,
LINE VOLTAGE = PHASE VOLTAGE
LINE CURRENT = 1.732 PHASE CURRENT

Answer / kavitha
