Abstract
An intelligent electronic device IED has enhanced power quality and communications capabilities. The IED can perform energy analysis by waveform capture, detect transient on the front-end voltage input channels and provide revenue measurements. The IED splits and distributes the front-end input channels into separate circuits for scaling and processing by dedicated processors for specific applications by the IED. Front-end voltage input channels are split and distributed into separate circuits for transient detection, waveform capture analysis and revenue measurement, respectively. Front-end current channels are split and distributed into separate circuits for waveform capture analysis and revenue measurement, respectively.
