You are so knowledgeable my friend God bless you
Many thanks for your useful videos
Keep them wonderful Videos coming Sir 👍.. & May GOD Bless you 🙏
Well explained
Keep up good work sir
You get new Electrical sub bro...
Great explanation...
Very nice
🎉
Very nice bro
Thank you sir. Could you do a video on transformer sizing for 200homes
Very clear explain for beginner in electrician, my role maintenance electrician so basic troubleshoot methods can you explain please sir.
Pls can you do full detail tutorial on conduit pipe laying for building and distribution of wires to circuit breaker. Thks
And please explain how the impedance will be different across houses. I mean if yellow house has all devices off at the moment. What will be the impact
Would the house with low voltage also suffer damage? E.g. motors that labour and overheat?
Please tell the protective measures as well
Sir,
How can we find resistance of a House
Thank you, but
I thought that phase to phase would be 400V at a phase angle of 120 degrees. In stead of 415V.
240/415V
230/400V
If i have a device in my house works on 3 phases and the neutral break down from the transformer, does this device will damaged too?
Depends if the Device/Equipment is tailored for 3Ø supply ?
Eg 3Ø ∆ Motor will work fine but if any Control circuitry that runs on Single Phase Eg PSU/contactor will probably get damaged.
To consider also if that Equipment all-together is protected by any means of Overvoltage Protection devices.
Broken neutral cannot damage 3 phase devices.
What if you link ur earth to neutral bar. From TT to t n c s.what will happen
It it NOT for you to simply "link" your own TT Earthing to N-bar to make it so called TNCS🚫
TNCS is defined by the Integrity of the PEN Supplied by the Electricity Supplier deemed fit to be used as "Protective Earthing" within Premises.
If you are Adding a Supplementary Earthing (by adding Local earthing rods to Strengthen the PME network) to your TNCS supply, that is another different story.
Assume your earth electrode is corroded or no continuity. You don't know this as the linked neutral was acting as earth. One fine day your service neutral floats. Now no neutral no earth. In this scenario all your appliances will not work. But the metal bodies will get energized due to looping. (phase to neutral to earth to metal bodies). You touch your fridge and die! Hope this helps.
