I Want the Data for the Earth and Short Circuit Data in DC System

08/14/2015 7:58 AM

I am working on a model for fault diagnosis in DC system. so to validate my model I need the data for short circuit, open circuit and earth fault.I mean how the resistance changing at the fault point. For example

if the Positive pole is earth at any point "A' then how does the resistance change between point/ Terminal 'A' and ground (earth)

Not enough information posted for me to help you.

You must first know the voltage applied and what type of circuit the voltage is being applied to.

Once you establish this information you must then know or assume fault conditions then solve for and plot the values following/using Ohm's law. E=IR I=E/R R=E/I

Please explain how a car battery or my flashlight differs from your system.

Short Circuit = 0

Open Circuit = ∞

Earth Fault = e.g. San Andreas

If Positive pole is at earth, then I think you are operating the battery at the telephone exchange.

You are a member here, or you could not open such a blog (I am told, though I have not tried to doit!).

Why are you anonymous? Afraid of looking stupid. Well to my mind, such a post simply proves it!!

I will not help you due to that, though I do know exactly what you need to do!!

It is nothing difficult and has been known for many years (as I am sure many here also know!!)

I know. You don't!!

Who are you?

Well said, I would have just pointed out the "This forum is not for getting other people to do your homework for you" rule and moved on.

You wimp! Insult his mother or something. He's AP#1, and AP#1 never deserves any respect.

And why does Anon. Poster number two have to be a complete a-hole to AP1 so often?
