Answer Posted / prashant singh
due to any cause phase and neutral are connected, then due
to less resistance high current will flow throw the wire.
the amount of current is several times high and it will
affect the system which connected to the wire. when high
current is flow due to power loss wire is heated and
damaged. the other effect is sharp arcing which is produces
due to high current density.

Why AC current leads voltage in capacitor and how?
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

why we use Test Terminal Block in 11 KV and 33 KV electrical panels.
how does the terminal voltage of transmission lines increase when a capacitor is connected???? This happens not only in transmission lines but also in all circuits. How??? When a capacitor is connected in a transmission line, capacitor also takes energy from the same supply. But how is it able to increase the terminal voltage??? Practically What sequence of events happen during increase in voltage???
