Delta connection line and phase current
WebIn the case of the Star Connection, the Line Voltage is √ 3 times the Phase Voltage, but the Line and Phase Currents are the same. Whether a Star or Delta Connection is used, the same formula (below) is applied to a 3 phase circuit: P = √ 3 x line voltage x line current times cos ø (power factor). Web12,960V. A three phase load has a voltage of 240 V at a phase current of 18 A. What is the apparent power of this load? V = 415.68. A = 18. If the loading question 7 is connected in wye, what would be the line voltage and the line current supply in the load? 104.3. An alternator with a line voltage of 2400 V supplies a delta connected load.
