Using Current Transformers with the 78M661x

Abstract: This application note describes using current transformers (CTs) with the Teridian 78M661x family of energy-measurement ICs in a measurement system. The following topics are discussed: current transformer background; burden resistor selection; phase error and compensation; selecting a current transformer; system calibration; and measurement results. A design example is included to itemize the design process. Calibration considerations and performance test data follow.
