ABSTRACT:
An electric wiring simulation device1of the present invention includes an input device2; a display5; a characteristics information data base4storing parts information on parts and wirings, discharge characteristics of a power supply, current-prearcing time characteristics of protecting parts and current-smoke time characteristics of the wirings; an assigned path searching unit11searching an assigned path between a short-circuit point and the power supply on a test object circuit; a current value calculating unit12calculating a resistance value on the assigned path based on the parts information, and calculating a short-circuit value based on the resistance value and the discharge characteristics of the power supply; and a judging unit13judging whether or nor each protecting part is fused or etch wiring smokes based on the current-smoke time characteristics and the current-prearcing time characteristics, at unit time intervals.
