what happens when a power transformer neutral earthing
broken???
Answer Posted / privin p v
according to KCL midpoint of a star connection is zero potential.If the load of the transformer is balanced nothing happen while neutral earthing broken.But in case of any unbalancing occurs there is no way to go the circulating current and heat occurs.It will damage the transformer

If you don’t have coal, salt and copper, then how would you earth your connection temporarily at a camp site.?
a)In a 3-phase 4-wire circuit, a circuit breaker is selected to protect the circuit whose highest fault level is 6.6 MVA. Determine the required minimum breaking capacity in kA. (Note: Covert 3-phase power in terms of kA to find answer.) b)Using the below, determine the required minimum making capacity in kA as a “peak value”. Rate breaking capacity (Icn) ka: Icn<= 1.5 Factor = 1.41 1.5
