2. Signal generator - Wikipedia

   en.wikipedia.org/wiki/Signal_generator

   A signal generator is one of a class of electronic devices that generates electrical signals with set properties of amplitude, frequency, and wave shape. These generated signals are used as a stimulus for electronic measurements, typically used in designing, testing, troubleshooting, and repairing electronic or electroacoustic devices, though it often has artistic uses as well.

3. Micro hydro - Wikipedia

   en.wikipedia.org/wiki/Micro_hydro

   Micro hydro is a type of hydroelectric power that typically produces from 5 kW to 100 kW of electricity using the natural flow of water. Installations below 5 kW are called pico hydro. [1] These installations can provide power to an isolated home or small community, or are sometimes connected to electric power networks, particularly where net ...

4. Generator (mathematics) - Wikipedia

   en.wikipedia.org/wiki/Generator_(mathematics)

   Generator (mathematics) The 5th roots of unity in the complex plane under multiplication form a group of order 5. Each non-identity element by itself is a generator for the whole group. In mathematics and physics, the term generator or generating set may refer to any of a number of related concepts. The underlying concept in each case is that ...

5. Reactances of synchronous machines - Wikipedia

   the sub-transient state is the one the generator enters immediately after the fault (short circuit). In this state the armature flux is pushed completely out of the rotor. The state is very brief, as the current in the damper winding quickly decays allowing the armature flux to enter the rotor poles only. The generator goes into transient state;

6. Electric generator - Wikipedia

   en.wikipedia.org/wiki/Electric_generator

   Electric generator. U.S. NRC image of a modern steam turbine generator (STG). In electricity generation, a generator[1] is a device that converts motion-based power (potential and kinetic energy) or fuel-based power (chemical energy) into electric power for use in an external circuit. Sources of mechanical energy include steam turbines, gas ...

7. Tesla's oscillator - Wikipedia

   en.wikipedia.org/wiki/Tesla's_oscillator

   An oscillator that was among the exhibits Tesla demonstrated at the World's Columbian Exposition in 1893. Tesla's electro-mechanical oscillator is a steam-powered electric generator patented by Nikola Tesla in 1893. [1][2] Later in life Tesla claimed one version of the oscillator caused an earthquake in New York City in 1898, gaining it the ...
