Recording data

This is the data in a day.Power being cut off, the system can restore in a few minutes.  Moreover, its generator continue to generate, however water pressure suddenly changes.The system can indicate the data Correctly.Therefore, the system doesn’t need a dam, simplifies its maintenance.

• With onsite test the “STREAM” with IITRooRkee, extend to new segment area of turbine in Japan(from ultra low head to middle). 

• Reclamation of new market in Japan by recovering the lost Jap turbine know‐how and the control of electricity.turbine know how and the control of electricity.‐ Cross flow, Pelton turbine etc.‐ up to 20kW, 200kW respectively

• Controlling technique can use both OFF‐grid and ON‐grid.‐ Starting local‐on site test at “Shiraito water fall.” ２０１４．３‐
