UK www.leturbines.comPage 14 of 28Turbine OperationThe LE-v150 turbine is based on a simple design for ease of installation and reliable operation. Youmay notice the following behaviour during normal operation: Cut-in - The turbine will not begin to charge the batteries until the rotor is spinning atapproximately 120 RPM. Whilst operating below this speed, the turbine will be ‘off-load’and freewheeling. Once the turbine output voltage becomes equal to the nominal batteryvoltage (at around 120 RPM), the turbine will come ‘on-load’ and begin to deliver currentto the batteries. During the off-load stages of rotation, the rotor blades rotate very freely.This allows the rotor to build up speed and allows aerodynamic lift to be generated by theblades. Normal Operation - Once the rotor is spinning at 120 RPM, current will be delivered to thebatteries. As the rotor speed increases, so too will the current and voltage. Shut Down (If Run / Stop switch is fitted) – A run / stop switch is not required with theLE-v150 turbine but one can be installed if desired (see appendix 2). By activating the stopswitch, the output cables of the turbine are ‘shorted’ together. This effectively puts aninfinite load on the generator causing the turbine to stall. When the stop switch isactivated the turbine may still rotate slowly during high winds, but the rotor blades will notbe able to build up any significant speed. It is not recommended that the stop switch isactivated whilst the rotor is spinning at high speed. This sudden braking action will stressthe blades and other components. Only activate the stop switch during a ‘lull’ when therotor is not spinning excessively fast. High Winds - Every effort has been taken to ensure that the LE-v150 will withstand theforces exerted by strong winds. The turbine will continue to generate power whilstsurviving the immense forces that are exerted by high winds. The LE-v150 Extreme isdesigned for locations where winds regularly gust to over 27m/s (60mph). |
