Abstract :
In this paper a realization of a precise electrical power and energy meter is presented. The fundamental of the described solution is an application of the “time division” multiplier. In this paper the technical improvements are described in order to achieve a higher accuracy. The achieved accuracy is better than 10-4 for sinusoidal input signals with the frequency of 50 Hz
