neutral is used for safety......when there is a earth fault
occurs by connecting the device in neutral we can sense the
fault. Also to avoid multiple ground faults.To avoid arcing
ground in which if there is a fault between phase to earth
arc is produced due to which current flowing to ground is
very low, overcurrent can not operate on this small current
hence connecting the device in the neutral we can avoind
the high arcing grounds.For core balancing also neutral is
used.

According to IEC60034-14, When the vibration monitoring system required for motor Bearing. above which KW, it is required? and for what type of bearing the vibration probe is provided.
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
