Abstract :
The procedure developed to introduce a tone superimposed to the voltage of the fundamental signal set in the electric power system is showed in this paper. The general configuration of the whole project and a more particular view on the different stages of the circuits are considered as systems. A deeper study from the electronic point of view was done, so working from scratch an elemental circuit was used to validate the coupling operation between the 50 Hz signal and the generated one. The first test carried out is fully detailed and also relevant information from the results are pointed out to understand the evolution that lead the new developed circuits.
