Abstract

As to the indirect-grounded fault of low-voltage network in mining, the selection device based on DSP is designed according to the principle about the dissimilarity of polarities and magnitudes of voltage and current between the healthy circuit and the faulty circuit, so as to locate the fault circuit promptly. This device, with its high reliability and strong anti-interference ability, is suitable to be used in the low-voltage network of the neutral point ungrounded or with the arc suppression coil over the ground in mining.
