We have a 11 kv transformer which is a non oil based transformer which gets trip again and again and they it's getting earth but the other transformer in the society don't what could be the problem
Is there any advantage to separate neutral and body earthing for consumer applications with "class I" appliances with RCD protection ? ( will it improve touch voltage and risk of fault on one earth effecting the other? Or decrease electrical noise on the body earth terminal for it devices?)
Yes. There are advantages to having separate neutral and body earthing. Also, separating neutral and body earthing can improve touch voltage, reduce the risk of fault on one earth affecting the other, and decrease electrical noise on the body earth terminal for IT devices. If a fault occurs, such as a live wire coming in contact with the exposed metal parts of the appliance, separating the neutral and body earthing can help. It will ensure that the fault current flows through the protective earth conductor, triggering the RCD and cutting off the power supply. This can reduce the risk of electric shock to the user. Therefore, it will improve safety, reliability and reduce fire risk.
Hey Tanishq, Protective multiple earthing is not allowed in India. Here, the TN-S earthing system is used. In this system, the Ground Conductor & Neutral Conductor are separate throughout the distribution system.
@@AxisElectrical But isn't PME just Neutral bonding with a separate earth rod at the consumer's main distribution panel, I am not talking about multiple PE-N bonds in the sub-panels.
@@AxisElectrical but we don't get earth from the DISCOM and the distribution transformer's earth impedance and the supply loop impedence is high enough to cause unacceptable high voltage between the Neutral and earth.
Hey Dauda, Procedure for your house earthing will depend upon factors like Soil Resistivity, however here's a generic video for your understanding: Earthing for Home: th-cam.com/video/HB3jmH2rz94/w-d-xo.html To check your Home's Earthing: th-cam.com/video/6WzpKSPeE08/w-d-xo.html
🎉🎉🎉super
Thanks Lokesh!
I personally like your lessons they are enjoyable
Thanks!
Wonderful presentation..please also tell how far should earth pits be from each other.
Thanks, I am glad you liked our presentation!
So earth pits should be 2 * Length of your Electrode.

Hey Avinash,
Let's connect on email to discuss to discuss this.

@@AxisElectrical thank you for the response
super.sir
Thanks Pandiyan!
Is protective multiple earthing allowed for consumers in India? Or do we have to treat it as TT system?

What are the procedure for house earthing
Hey Dauda,
Procedure for your house earthing will depend upon factors like Soil Resistivity, however here's a generic video for your understanding:

How many earthings are done on the post where the distribution transformer used in the distribution line
Hey Ram,
Generally two earthing for body and two for neutral.
Earth mat
Thanks again Dahiru - we’ve done this video as well: Earth Mat for Substation
