Wide-range generator for research of high-frequency parameters of mine power networks

Abstract

Complex mechanization and automation of production processes in underground workings is associated with the transmission of control and monitoring signals from control points to mechanisms and back. Sealing power networks with telemechanical signals significantly reduces the number of control cores in power or control cables or completely eliminates them, which is especially important in underground workings. One method of transmitting telemechanical signals is the densification of power networks with high frequency currents. In order to determine the optimal for signal transmission high-frequency parameters of networks, it is necessary to study these networks in a wide enough frequency range ...
