This paper is devoted to the smart grid era which requires not only knowledge in the field of electric energy but also of many other fields like information technology, communication, control and automation, education, and nanotechnology. This universal effort will be effective if and only if the management and control of energy includes reliable information from accurate measurement methods and voltage and current sensors.
