Abstract
A system for measuring current includes a current monitoring system comprises a current sensor configured to sense a first current passing through a conductor and a voltage conversion device coupled to the current sensor and configured to receive a second current from the current sensor and convert the second current into a first voltage. A first scaling circuit is coupled to the voltage conversion device and configured to convert the first voltage to a second voltage proportional to the first current based on a first scaling factor, and a second scaling is circuit coupled to the voltage conversion device and configured to convert the first voltage to a third voltage proportional to the first current based on a second scaling factor, wherein the second scaling factor is different from the first scaling factor.
