The main switchboard of a 400/230 V industrial installation is directly supplied from a 500 kVA transformer which has a prospective fault current of 13,990 A per phase.
Sub mains supply a distribution board from the main switchboard.
The following information is known:-
Impedance of the Consumers Mains = 0.0040 ohms
Impedance of the Sub mains cables = 0.025 ohms
Determine the prospective fault current at:-
(i) The main switchboard
(ii) The distribution board
Work impedance's to 5 decimal places and explain all calculations.
Find prospective fault current?
