- Abstract
This paperwork represents a mathematical calculus method for deriving the RMS value of an analog signal which has a DC offset. The analog signal is generated either by a current transformer based sensor or a voltage transformer based one, which is used for an off-grid household power consumption monitoring system. The received analog signal values are converted by the microcontroller's ADC into digital values. Based on a mathematical modelling of the signal, an algorithm is thus developed to be uploaded into a microcontroller based embedded device, which further converts the digital values into comprehensive numerical values about the measured power consumption.
