Resistance Model of Mining Communication Cables

摘要

Mine monitoring system uses the mining communication cables as the transmission lines. However, there has no unified electrical parameter model of communication cable. In this paper, based on the resistance model of BT Model #0 and the values of the resistance model parameters of cables recommended by ETSI, the curve fitting method is adopted to determine the resistance model parameters of mining communication cables, then the resistance model is deduced. Through theoretical analysis and experimental comparison, it is verified that the resistance model effectively simulates the cable resistances with different frequency range.
