The description of the main and auxiliary equipment of the ЭКС-100 Power-cavitation test rig of OJSC Turboatom’s hydraulic turbine laboratory is given. The test rig is an installation with a closed circuit of water circulation. The selective tests as well as acceptance tests of hydraulic turbines, pumps and reversible hydraulic machines are performed at the test rig. During the testing the energy, cavitation, pulsation, power, erosion characteristics of water passages of model hydraulic machines are registered as well as the whole work package in the scope specified by the IEC 60193 Code of the model acceptance test of hydraulic turbines and reversible hydraulic machines. The broad operational capabilities of the test rig, steady operation, equipment with miscellaneous devices and means of their calibration, automated measuring system and mathematical treatment of results allow to obtain the hydraulic machine models’ characteristics with a high degree of reliability, provide adherence to the modeling criteria stipulated by the international IEC60193  Code and other requirements applicable to acceptance tests. It is demonstrated that the hydraulic characteristics of the test rig and applicable measuring equipment as well as used graduation procedures of primary detectors provide a precision of measurements corresponding to the requirements of IEC 60193 Code of the model acceptance test of hydraulic turbines and reversible hydraulic machines. The test rig has a calibration certificate and is officially accepted by means of comparison tests of the same hydraulic model turbines at the laboratories of NEL (Great Britain) and СКD Blansko (Czech Republic), during those tests a fine precision is obtained.
