#88588 - Error depends on phase angle Responding to: ???'s previous message |
Ali:
Power = V x I x Cos (Angle+Error) Where Angle = Actual phase angle between V and I Error is your time measurement skew error. Skew Error is 0.89 degrees on a 50Hz system. Thus if actual phase angle is 0 degrees the power "skew error" will be 0.02% but if phase angle is near 90 degrees the error is 1.5% Peter |
