Coil, Current Transformer (CT) based AC current measurements using fast ADC sampling of waveform
Mesure currents, iRMS and similar with a current transformer or coil. Requires a simple bias circuit that ensures that the votlages fed to the ADC is swinging around a certain dc-offset; and this is then ran through a resistor to turn the current into a voltage. Actual curernt measurement is then made by fast sampling the waveform. Assumes relatively slow AC curernts (few 100Hz), such as typical household mains power supplies (50hz, 60hz)
