Comparison of electrical measurements between different devices for smart meter applications

The integration of smart electrical networks aims to better respond to faults, and distribute and control energy consumption, all of this would be difficult to achieve without the functions of smart meters that allow the sending of information between electricity companies’ services and the consumer, which is why it is important to guarantee the reliability of the information that is shared. In this work, the validation of the EVM430-F6736 meter and the PZEM-004T sensor is carried out concerning conventional devices for measuring electrical variables such as multimeters and wattmeters. The results show the error percentages between the measurements of the different devices.
