Abstract: The paper deals with model tests for a manifold of a hydropower station with 4turbines installed, to determine relevant energy losses. Construction of model, monitoring equipment and basic suggestions are discribed. Measurements and evaluations at various load cases are presented and commented on, especially the phenomenon of negative energy losses.
