Device and method for overcurrent protection in an electric power distribution cabinet |
摘要 |
The device has a switching unit (20) and an unit (23) which calculates the absolute value of the difference between the current entering this cabinet and the corresponding current exiting this cabinet, for a mean harmonic of these two values. There is also a comparison unit (24), which controls the opening of the switching unit if this absolute value is greater than a predetermined threshold value (5). |
