I want to purchase or construct 3 clip on current transformers that
will produce a small current in a parallel connected resister. This
voltage will be rectified using full wave rectifier, and then passed
to the input of a voltage monitor card that will used to monitor line
current in the cables that are running through the transformers.
First of all will this work? I am wondering if there will be a
linearity problem due to the voltage drop in the diodes or maybe
something else. The input resistance of the monitor card is 1 Mohm
and maximum 30 Vdc.
Can anyone see other problems with this design. Accuracy needs to
be within 2 or 3 %.
