2. Short circuit ratio (electrical grid) - Wikipedia

   en.wikipedia.org/wiki/Short_circuit_ratio...

   Hence, such a grid is known strong grid or power system. A power system (grid) having a lower SCR has more vulnerability to grid voltage instability. Hence such a grid or system is known as a weak grid or a weak power system. Grid strength can be increased by installing synchronous condensers. [10]

3. Alternator - Wikipedia

   en.wikipedia.org/wiki/Alternator

   The main alternator is the larger of the two sections, and the smaller one is the exciter. The exciter has stationary field coils and a rotating armature (power coils). The main alternator uses the opposite configuration with a rotating field and stationary armature. A bridge rectifier, called the rotating rectifier assembly, is mounted on the ...

5. Magneto - Wikipedia

   en.wikipedia.org/wiki/Magneto

   A small residual field in the iron armature of the field coils acted as a weak permanent magnet, and thus a magneto. The shunt wiring of the generator feeds some of its output current back into the field coils, which in turn increases output. Because of this, the field 'builds up' regeneratively, though this may take 20–30 seconds to do so fully.

6. Excitation (magnetic) - Wikipedia

   en.wikipedia.org/wiki/Excitation_(magnetic)

   Alternator of 1930s diesel generating set, with excitation dynamo above. For large, or older, generators, it is usual for a separate exciter dynamo to be powered in parallel with the main power generator. This is a small permanent-magnet or battery-excited dynamo that produces the field current for the larger generator.

7. Alternator (automotive) - Wikipedia

   en.wikipedia.org/wiki/Alternator_(automotive)

   Alternator (silver) mounted on a V8 engine. An alternator is a type of electric generator used in modern automobiles to charge the battery and to power the electrical system when its engine is running. Until the 1960s, automobiles used DC dynamo generators with commutators.
