In order to examine the efficiency levels of the turbines, the following tests have been carried out on both the big and the small turbines of the mini-HPP. Operation tests on the big and small aggregates have been performed with the loads of 40, 50, 60, 70, 80, 90 and 100 %.

Conclusions: At the efficiency level of 85%, the measured small turbine efficiency level differs by a single point of nominal value, i.e. 250 l/s. It is important to note that the correction to the decline's net worth of 50 m has been performed using a topographic chart of the large turbine, shown in one of the images, taking into account the constant level of openness. The existing topographic chart (a feature provided by the manufacturer) does not match the measured values, so it is advisiable to conduct additional measurements with two additional net drops in order to make a new topographic chart. Such a chart would help make more accurate corrections to the net drop, and it could be used in making exploitation dependency on the plant.

Equipment used for the measurement of the level, pressure, electric power of the aggregates, and the flow through the turbine is shown in Figures 1-5.
