Description Pelton turbineis animpulseturbine, the turbineis driven by the kinetic energy ofthe water. Spray(jet) on thehigh-speed waterbucketandrunnerafterrunnermovesthe waterat low speed, which meansmost ofthe energyis notabsorbedbythe runner. The water pressurein and outof the bladeisatmosfir.Turbinpressurepeltonisthe best exampleof theimpulseturbine. Theturbineis operatedbyoneormorejets(nozzle) of waterinto thebucketat thecenteraround theparameterof therunner. Power comesfrom theforceof waterfromhigh-pressure impingementimpulseturbinebucketsso named turbin pelton. One of themost importantcomponents of pelton turbin is nozzle, the distancebetween thenozzleand the bladecanaffect the bladeturbinerotating speed. In addition, the distance between thenozzleof therunnerdeterminesthe point offallingwater, because thenozzlemusthavea proper distanceso thatturbine bladescan receivea goodimpulse. From the test results influence the distance the spray nozzle to the rotation runner and the electric power generated in the prototype turbine Pelton, with a distance of spray 50 mm, 60 mm, 70 mm valve opening is 30?, 60? and 90?, it can be concluded as follows: Acquisition rate of rotation runner Pelton turbine prototype that is highest at a distance of 50 mm spray nozzle when the valve opening 90 with a rotation rate of 428.67 rpm runner, generating electric power of 10.57 watts, with the fluid flow rate (Q) generated as much as 0.00082 m /s, while for the lowest round at a distance of 70 mm when the spray valve opening 30? with 381.00 rpm rotation speed, generating electrical power 9.84 Watt, the fluid flow rate (Q) generated as much as 0.00074 m/s. fluid flow velocity higher acquisition prices are at a distance of 50 mm semprotm nozzle when the valve opening is 13.93 m/s 90. With the mass flow rate of 0.82 m/s. In the case of fluid mass flow rate the greater the valve opening, the greater the mass flow rate of the fluid and the fluid flow generated. The highest result of the mass flow rate of fluid that is at a distance of 50 mm when the spray valve opening 90 obtain fluid mass flow rate of 0.82 kg/s and produce a flow rate (Q) as much as 0.00082 m/s.
