turbined water draining transmission to consumers voltage decrease high-tension electricity transmission head of water water under pressure transformation of mechanical work into electricity transmission of the rotative movement to the rotor rotation of the turbine production of electricity by the generator energy integration to the transmission network voltage increase energy transmission at the generator voltage supply of water

turbined water draining click to hear : turbined water draining

After passing through the turbine, the water rejoins the watercourse.

transmission to consumers click to hear : transmission to consumers

The electricity is carried to areas of consumption by low-voltage distribution lines.

voltage decrease click to hear : voltage decrease

Before integrating the electricity into the distribution network, the voltage is progressively decreased to 240 V.

high-tension electricity transmission click to hear : high-tension electricity transmission

Using high-voltage lines to transmit electricity over long distances reduces the strength of the current and, as a result, energy losses.

head of water click to hear : head of water

The dam raises the water level to create a vertical drop along the length of the penstock.

water under pressure click to hear : water under pressure

The water takes on energy as it flows down the penstock and is carried with force to the turbine.

transformation of mechanical work into electricity click to hear : transformation of mechanical work into electricity

The generator converts water power into electricity.

transmission of the rotative movement to the rotor click to hear : transmission of the rotative movement to the rotor

The movement of the turbine is transmitted to the rotor by the shaft.

rotation of the turbine click to hear : rotation of the turbine

Flowing water applies pressure to the turbine’s blades to make it turn.

production of electricity by the generator click to hear : production of electricity by the generator

The generator produces electricity through the movement of the rotor in the stator.

energy integration to the transmission network click to hear : energy integration to the transmission network

The electricity produced is integrated into the network.

voltage increase click to hear : voltage increase

At the outlet end of the power plant, the transformer increases the voltage; this reduces energy losses during transmission over long distances.

energy transmission at the generator voltage click to hear : energy transmission at the generator voltage

Electric power produced by the generator is transmitted to a transformer at the power plant outlet.

supply of water click to hear : supply of water

Basin created by building a dam, which holds back a large volume of water.
