(measure current by current transformer and voltage by A'D converter) You will need A-to-D converters for both voltage and current! i dont find a way by means of which i can determine wheter the power factor is leading or lagging. Do you understand what those terms mean? ie what is the characteristic of the voltage and current waveforms that determines whether it is "leading" or "lagging"? Think of the words "lead" and "lag" in their normal, everyday (non-technical) English usage - that's the clue! From understanding what they mean, it should be obvious how to distinguish them! I am waiting for the solution if u can suggest Rather than just waiting, how about doing some thinking and some research? |
