Title: METHOD FOR TESTING THE WORKING ORDER OF A DC LINK
Abstract:
Disclosed are a method and an arrangement for testing the working order of a DC link (60) in a multi-voltage power network (50) comprising a d.c-d.c. converter (56). According to said method a fixed current is set and supplied to the DC link (60) and a voltage applied to the DC link (60) is measured at temporally sequential sampling points, a capacity (64) of the DC link (60) being calculated from the measured voltage values, taking into consideration the intervals between the sampling points.
