Research on the Transmission System of Multi Frequency Electrical Resistivity Detecting

Abstract

Goaf detecting is of great significance to the safe operation of the power grid. The traditional detection technology has many disadvantages like single frequency transmission signal, low detection efficiency, anti-interference ability and so on, so they are not suitable for the detection of goaf under the transmission power line. This paper designs a multi frequency resistivity detection transmission system, which has a wide frequency range, rich frequency content, high detection efficiency. It also has the ability of anti-electromagnetic interference, more suitable for the goaf detection under power grid, and it is significant to ensure the safe operation of the power grid.
