Hydroelectric PowerISCAR, A World Leader in the
Renewable Energies Industry
Renewable Energy is collected from clean resources thatare naturally replenished on a human time scale suchas sunlight, wind, rain, tides, waves, and geothermal heat.
Hydro Power is power derived from the energy of falling
water or fast running water, which can be harnessed for
useful purposes.

ISCAR, a company with many years of experience in theproduction of metal cutting tools, offers unique solutions
for the new generation of industries. As a leader in providing
productive and cost effective machining solutions,
ISCAR strives to be up to date with all the new trends andtechnologies which are a part of a brighter, greener future.

A Pelton wheel is an impulse-typewater turbine invented by American
inventor Lester Allan Pelton in the1870s. The Pelton wheel extracts energy
from the impulse of moving water, as
opposed to water's dead weight likethe traditional overshot water wheel.
Pelton wheels are the preferred turbine
for hydro-power where the available
water source has relatively high hydraulichead at low flow rates. Pelton wheels
are made in all sizes. There exist multiton Pelton wheels mounted on verticaloil pad bearings in hydroelectric plants.

The Francis turbine is a type ofwater turbine developed by James B.
Francis in Lowell, Massachusetts. It is
an inward-flow reaction turbine thatcombines radial and axial
flow concepts.
Francis turbines are the mostcommon water turbine in use today.
"The Francis design has been usedwith head heights of from 3 to
600 meters, but it delivers its best
performance between 100 and 300
meters" and are used primarily forelectrical power production.

The Kaplan turbine is a propeller-type water turbine with adjustable blades. It wasdeveloped in 1913 by Austrian professor Viktor Kaplan, who combined automaticallyadjusted propeller blades with automatically adjusted wicket gates to achieve efficiency
over a wide range of flow and water level. Kaplan turbines are now widely usedthroughout the world in high-flow, low-head power production.

A wicket gate, or guide vane, is a component of water turbines to control the flow ofwater that enters the turbine. A series of small openings of the wicket gates surround theturbine. When the wicket gates are opened wider, more water will flow into the turbine
runner which results in higher power output. The control of wicket gate opening andclosing will allow the output energy generated by the turbines to be controlled to matchthe desired output energy levels.
