Any electrical machine, new or refurbished, must be subjected to tests to verify the compliance with technical requirements imposed by standards and, eventually, to determine some experimental data needed for the machine operation. This paper presents in site experimental determination of the operation electrical parameters of the hydro generators that equip a hydropower plant: the active power of the generator, the voltage and stator current, the characteristics and parameters of the system
