Abstract For the application of inspecting the construction status of distribution network poles, this paper proposed a novel detection technology for base plates, pulling plates, chucks (abbreviated as BPC) which are buried together with the power poles based on exerting external current excitation. The detection system consists of lead wires for BPC, an excitation generating circuit, a signal receiving coil, a signal conditioning circuit and an embedded processor. Compared with the traditional transient electromagnetic method, this technology is more suitable for detecting BPC which are buried shallowly, with higher sensitivity for depth changes and higher signal-to-noise ratio. Moreover, it can judge… More >
