Short Circuit / Fault Analogy
Short Circuit / Fault Analogy
(OP)
If someone would ask you to explain (dummify) what happens in a distribution circuit during a fault, how would you explain it to them?
For a lot of people, it is very important to have certain concepts like faults broken down to simple terms using analogies, so please share your understanding using basic language.
Thanks,

Before the fault the tap (power station/transformer) is on and all the sprinklers (loads) are happily working away. A mower hits the hose somewhere creating a slice (fault) and a heap of water rushes through the slice, limited to what the tap (transformer) can force through the hose (series impedance). The pressure (voltage) in the system falls while the water flow (current) between the tap and slice is near its maximum. If the hose can be pinched shut (breaker opens) just upstream of the slice, only the sprinklers (loads) downstream of the breaker will be affected.

The smoke theory of electricity states that electricity is smoke contained within the wire. Everything works well as long as the smoke stays within the wires, but anytime the smoke gets out of the wires, things stop working. Anytime you see something electrical letting the smoke out, you can be pretty sure that it won't work any more.

Liteyear it seems like there a multiple instances where you can use the water analogy to explain electric theroy.
Thanks again.

Have you thought about an how to include the beer (reactive) power into the analogy?

Wear leather gloves. Do not wear polyester, nylon, or other meltable / flammable clothing. Keep a bucket of water or a fire extinguisher nearby. Eye protection required, full-face shield eve better. Non-flammable place to set the wool on before applying battery. Well-ventilated room or outdoors. An OSHA guy would require me to be in a welder's leather apron.
In other words, BE SAFE! Consider the temperature needed to melt steel. You'll be doing a lot of it.
Best to you,
