4.2.1 Formulas
This section describes the formulas used for the voltage, current, and energy calculations.
4.2.1.1 Voltage and Current
As discussed in the previous sections, simultaneous voltage and current samples are obtained from three independent ΣΔ converters at a sampling rate of 3906 Hz. Track of the number of samples that are present in 1 second is kept and used to obtain the RMS values for voltage and current for each phase.
