Designing a Protective Grounding System Simulator for TT, IT, and TNC(S) Circuits

Hi to all dear members of EEWeb!

This summer, I have a required final year project for me to graduate as an electrical engineer. My topic is to design and implement a simulator of a protective grounding system that contains 3 types of circuits. These are: TT, IT, and TNC(S). And adding the adequate protective circuit and so on. . .

I found some data but it still is not enough. I would be glad if you could help me out.

Thanks in advance!

I see that here are no answers...
The reason for this could be because its difficult to understand what you are looking for. Could you give more specific information what data you are looking for and what exactly your simulation should do. What exactly will be simulated ? (Maybe Shortcircuit current ? ) There is a lot of data available on the Inernet (CB, RCB, Motorstarters etc..., look for ABB, SIEMENS, SCHNEIDER, Merlin Gerin, also look for applicable national or international Standards like IEC 60364 series especially IEC 60364-4-41)

hi, welcome to this forum site, your project for grounding system simulator having three circuit that is TT, IT and TNC is not perfect if you want make this project you give more information about this "projects. (Electronic minor and major projects solution)":http://www.suryaengineers.tk

thnks a lot for ur help .....
here is the details .

my purpose is to implement a simulator ( circuit) that describes how the 3 types of

grounding are working ...
for educational purpose .. that is i will let this circuit in my isntitut as a good

example of grounding

the steps are ...
i need power supply ..
a load ( resistors) ...
and i need protective elements ...
and each type of grounding as a specific adequate protective element ....
example :
the TT grounding type needs the differential relay ...
the IT needs impedance controller and so on .....

so i need those details ..
i want to simulate them in simulink (matlab) before implementing the circuit ....

hope it is clear ...
please help me soon ....
time is running ...
