Hi,
Whilst I understand the following in terms of identifying the phase and line voltages etc please could someone advise me what I would put into the calculator for cosθ as detailed below. I seem to understand it and then they throw this in for good measure .
In case of delta conneted load in above fig(a) the total active power is equal to three times the power of one phase.
Since the line current in the balanced delta connected loads is
substituting this eq the total active power becomes
Thank you very much for your help!
