Answer Posted / kunal
electrical supply system is often connected to earth
ground, ground and neutral are closely related. Under
certain conditions, a conductor used to connect to a system
neutral is also used for grounding (earthing) of equipment
and structures. Current carried on a grounding conductor
can result in objectionable or dangerous voltages appearing
on equipment enclosures, so the installation of grounding
conductors and neutral conductors is carefully defined in
electrical regulations. Where a neutral conductor is used
also to connect equipment enclosures to earth, care must be
taken that the neutral conductor never rises to a high
voltage with respect to local ground

Thermal withstand capability under full short circuit conditions, in terms of number of times of occurrence of short circuit and corresponding anticipated percentage reduction in transformer life.
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
