The use of a new water turbine to meet the needs of electrification in isolated places in the Amazon region has been successful. It is highlighted that this technology was designed by empirical development and its use also is based on such techniques. This paper pro-poses a mathematical model using the theory of Bond Graph, and an experimental evaluation in reduced model of the hydraulic turbine, to characterize their operating limits. The dynamic control techniques are adopted in applied mathematical model and a bench was developed for experimental trials in hydraulic pico-turbines. They are reported as result: the mathematical model and hill charts containing a total of 4200 points, with power and efficiency values depending on the speed. The simulation results support the conclusion that the model has as answer a quick stabilization that happens as a damped form, another conclusion is that this turbine has a comprehensive use of potential because there were no significant variations in the values of their income, remained at approximately 79 %
