When to Perform an Eight-Step Door Test and a Five-Step Door Test

After the installation and debugging of the generator set is completed. The eight-step gate test is carried out under the rated water head of the generator set and is used to detect whether the mechanical and electrical properties of the hydroturbine generator set meet the design requirements. carried out under a non-nominal water height. By reducing the small water height reduces the speed of the water wheel, thereby testing the performance of the water turbine generator set under low water height to ensure the stability and reliability of the water turbine generator set. The specific timings of these tests are based on the conditions of the hydroelectric plant.
