Explanation Discussion: Write the expression for the total average power for Y-connected system or Δ -connected system. P = 3 V p I p cos θ (1) Here, V p is phase voltage magnitude. I p is phase current magnitude. θ is power factor angle. Write the expression for the total reactive power for Y-connected system or Δ -connected system. Q = 3 V p I p sin θ (2) For Y-connected: The relation between line phase parameters is, I L = I p and V L = 3 V p Substitute I L for I p and V L 3 for V p in equation (1). P Y = 3 ( V L 3 ) ( I L ) cos θ P Y = 3 V L I L cos θ Substitute I L for I p and V L 3 for V p in equation (2). Q Y = 3 ( V L 3 ) ( I L ) sin θ Q Y = 3 V L I L sin θ For Δ -connected: The relation between line phase parameters is, I L = 3 I p and V L = V p Substitute I L 3 for I p and V L for V p in equation (1)
