The increase in the number of companies and the incessant productive growth of the various economic sectors have increased programs that contribute to the sustainable consumption of electrical energy, all this in order to promote a culture of savings. The use of standardized and calibrated tools is essential, as they allow constant monitoring of the various electrical parameters of the industry. The prototype has a STM32F7 as a microcontrolled system for digital signal processing in real time, also, the choice of voltage and current sensors for the correct functionality of the same. The prototype can compete with commercial meters since its error range in tests is minimal, having an error of 4.73, 8.82 and 3.08 % in active power, 2.05, 0.97 and 1.79 % in apparent power and 7.69, 5.85 and 14.29 % in reactive power. With the results obtained it is concluded that the prototype is applicable, being this a viable and economic option for an energy audit, limited only by the amount of prototypes that can be created for a possible solution of application of the same one.
