I came across several discussions that made in past but I didn’t get the real question in my mind. When we run a voltage generator (dynamo, fuel generator, etc.) it produces voltages. If there is a load connected to the generator’s output, it will start to pull currents. If there is no load connected to the output, it will still produce voltage but there is no current that will flow through the output … So; zero times current and 220 times volt is equal to zero power… I am okay with that until here…
Here is my question is:
Is this situation harmful to the generator? what happens if we continue to run the generator with no load? Does it burn himself due to increasing inside temperature due to inside consumption such as friction, ventilation, etc. ? Is it dangerous to run a generator with no load? I also wondering this question with other generators such as solar cells…
So my point of the question is: what happens to the source if we don’t consume the generated electricity from the source?
In: Physics
A generator produces electrical currents from a rotating source. When you use the electricity it will slow down the input and if you do not use the electricity it will not do anything. There is usually a flywheel attached to the input in some way and if for example an engine is used to power a generator and you suddenly shut off the electricity the engine will spin faster and faster until it will turn down the throttle.
A big part of the issues with wind turbines and solar power is that these do not have a flywheel attached to the electricity grid like traditional power plants. So they are not able to easily store energy which is produced but not consumed in the same way.
