Abstract
An intelligent electronic device (IED) has enhanced power quality and communications capabilities. The power meter can perform energy analysis by waveform capture, detect transient on the front end voltage input channels and provide revenue measurements. The power meter splits and distributes the front end input channels into separate circuits for scaling and processing by dedicated processors for specific applications by the power meter. 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.
