Abstract
The invention is a means of fault detection and location for dc networks. AC systems attempt to measure the inductance of the line; this is not possible in a dc system. Instead, in this invention, the inductance is estimated from the initial rate of discharge of the current from the dc bus capacitor on the converter feeding the dc network. This will reduce the duration that a fault will exist, reducing damage and improving safety, as well as improving discrimination so giving a more reliable system.
