Abstract
This chapter consists of functions, calculations, and operations inside the standard energy measurement chips commonly available in the market. Signal conditioning, analog to digital conversion (ADC) and electrical parameter calculations are described step by step where the reader can get an overall idea on digital energy measurement. Signal conditioning includes filtering and effect of aliasing the sampled signal while ADC includes the sampling techniques and quantization noise reduction techniques. The calculation section elaborates the energy measurement, RMS voltage, RMS current, active power, reactive power, apparent power, harmonics measurements, line frequency, power quality measurements, and four quadrant operation. The calculations are based on sinusoidal conditions as well as non-sinusoidal conditions. Different types of energy measurement chips are compared with their energy and power calculations. Digital to frequency conversion (DFC) and communication protocols used in energy measurements chips are also highlighted.
