Micro Hydroelectric Generator
Single Nozzle T100-10DCT
T100-10DCT is a AC direct systems consist of a turbine-generator unit producing AC power which is used as needed. That is, it is fed directly to the appliances. No need of battery and inverter, T100-10DCT offers a complete water to wire system with integral turgo turbine, generator and valve flow control. Designed to deliver ready-to-use 115V/230V VAC power, it employs a brushless, special rare-earth permanent magnet alternator and therefore has a higher efficiency than ordinary alternator. Output voltage and frequency are controlled by the electronic load controller(with ballast). As little as 13 to 17 liter per second (l/s) falling 100 meter through a pipe can supply enough power to comfortably run a small household. This machine is compact, easy to install and requires little maintenance except lubricating the bearing every few months.
The tur go turbine was designed for families in remote areas to produce power for their households easily and inexpensively. These units have been incredibly successful and today thousands are installed throughout the world.
These turbines need very little water flow to run efficiently and produce significant power out. The standard configuration uses one nozzle.

Water is collected upstream from the turbine and channeled in a pipe down to the turbine location. At the turbine, the water passes through a nozzle, where it accelerates, strike the turbine runner, and turn a AC single-phase brushless permanent magnet alternator. A electric load controller is built on the alternator which stabilizes the voltage to 110V or 220V to protect electrical appliances during use. Installation is very simple and explained in the manual. Once installed there are no running costs and maintenance costs are very low.
If you feel you may have a suitable site, please email specific information on your actual site. The information that is required for a preliminary assessment is:
1. The volume of water flowing in your stream, expressed as liters per second.
2. The head (height of drop) of the falling water, expressed in meters.
3. The length of the penstock (pipeline) in meters.
Warranty: 2 years

Guide on How to Develope a Small Hydropower Plant
HOW DOES MICRO HYDROPOWER WORK?
Hydropower plants capture the energy of falling water to generate electricity. A turbine converts
the energy of falling water into mechanical energy. Then an alternator converts the mechanical
energy from the turbine into electrical energy. The amount of electricity a hydropower plant
produces is a combination of two factors:
1. How far the Water Falls (Head):
Generally, the distance the water falls
depends on the steepness of the terrain the water is moving across, or the height of a dam the water is stored behind. The farther the water falls, the more power it has. In fact, the power of falling water is ‘directly proportional’ to the distance it falls. In other words, water falling twice as far has twice as much energy. It is important to note we are only talking about the vertical distance the water falls – the distance the water travels horizontally is consequential only in expense of the system and friction losses. Head is usually measured in ‘meter or feet’.
2. Volume of Water Falling (Flow): More water falling through the turbine will
produce more power. The amount of water available depends on the volume of water at the source. Power is also ‘directly proportional’ to river flow, or flow volume. A river with twice the amount of flowing water as another river can produce twice as much energy. Flow volume is usually measured in ‘liter per second’, or ‘l/s’.
For Micro Hydro systems, this translates into two categories of turbines:
For high head and low flow volume sites, impulse turbines are the most efficient choice.
The power produced by an impulse turbine comes entirely from the momentum of the water hitting the turbine runners. This water creates a direct push or ‘impulse’ on the blades, and thus such turbines are called ‘impulse turbines’.
For low head and high flow volume sites, a reaction turbine is the best choice. The reaction turbine, as the name implies, is turned by reactive force rather than a direct push or impulse. The turbine blades turn in reaction to the pressure of the water falling on them. Reaction turbines can operate on heads as low as 2 feet, but require much higher flow rates than an impulse turbine.
