Abstract
A system for improving accuracy of an intelligent electronic device operable to monitor electrical energy using metering sensors is disclosed. The metering sensors may be tested to determine characteristic curves by simulating operating conditions. The characteristic curves may be developed and transferred to the intelligent electronic device or may be developed by the intelligent electronic device through self-testing. The intelligent electronic device may apply the characteristic curves during operation of the intelligent electronic device.
