Microhydropower Systems | Department of Energy water sprays out of the nozzle in a jet, striking the double-cupped buckets attached to the wheel. The impact of the jet spray on the curved buckets creates a force that rotates the wheel at high efficiency rates of 70–90%. Pelton wheel turbines are available in various sizes and operate best under low-flow and high-head conditions.
Influencing factors analysis on the detector output signal ...· During the operation of the converter station, the measured current may increase due to short-circuit faults. To analyze the influence of current increase on the detector output signal, the output signal of the detector is calculated when the measured current is 5000A, 10000A and 15000A, respectively, and the results are shown in Fig. 7.
