An advanced variant of an experimental method of investigating the blades torque using models of the Kaplan turbine runner was suggested. The investigation is based on using modern miniature electronics devices and wireless technologies. The experience of implementing the method suggested on the hydrodynamic test bench at IPMash NAS of Ukraine and the results of measuring the torque for a six-blade model of the PL40 runner are given. The torque was measured using a strain gauge transducers and an runner model developed by LLC Kharkovturboengineering specialists. Experiments on the hydrodynamic test bench yielded the values of blade torques for the entire hill diagram range. The torque for acceleration conditions, as well as the torque vs. centrifugal force values was measured.
