They deserve awards for acting skills ASAP!

Definitely no awards for acting.

Thaaaank youuuuuu

Fascinating

[@microrex21]

where can we get that meter..?

[@shubhchaudhari487]

One question about this concept always bother me ... When earth fault occures on any system.. How and why earth fault current flows back to service transformer neutral earthing point only ?? Why it is not diverted to any other way (considering the earths huge cross-section) ... In between the path of fault location and service transformer neutral earthing point, any conducting object might be exist then why fault current is not diverted towards that conducting object ?

[@sabrinashi1796]

This is under the concept of TNS system for a Wye connected secondary, the source transformer would have a separately derived system and serve both neutral and ground to the downstream loads, all the ground of downstream are tied back to the source transformer where the N and G are tied together. Downstream loads would not have separately derived grounds.

Good question. I also used to wonder about this and I came to this understanding: The fault occurred downstream of a particular transformer, this that transformer is now unbalanced. Other transformers are still balanced, and this they remain that way. In a sense, they have no room for this stray current. On the other hand, the "faulted" transformer does have room for it's"lost" current to return, in search of balance.

What a lesson .
