A smart detection system for power grounding grid based on GPR

Grounding grid is a kind of critical infrastructure to ensure safe and stable operation of the grid and the personal safety. Buried in the ground and limited by the surface buildings, the ground grid is inconvenient to be detected and maintained. In this paper, in order to overcome the difficulties in detecting the ground grid of the high-voltage transmission and substation, we studied a detection system based on ground penetrating radar (GPR), which can present intuitive visual images of the grid, makes accurate diagnosis to the ground grid, without power failure and dug. The design, installation and maintenance of norms detection of grounding grid used in high voltage transmission lines and substations is the foundation to ensure the safe operation of circuits and systems, grounding grid has the characters of large-scale, complex structure and laying deep. In practical engineering, the means for measuring the grounding grid are primitive, traditional methods for measurement are indirect measurement or excavation, with blindness, and large workload, low efficiency and inadequate measurement accuracy. Meanwhile, the high-voltage transmission lines and substations is bearing the heavy responsibility of national production and people's lives, whose maintenance without power will inevitably bring many economic losses that makes the actual operation difficult. In this paper, to solve the current difficulties in the detection of ground grid used in high-voltage transmission lines and substation, we present a detection system based on ground penetrating radar (GPR), designing and forming a kind of device to the corresponding test(1-2). Meeting the electricity systems limitation of simple, accurate, free on-site operating conditions, the system for the grounding grid achieves diagnosis and practical detection for the grounding grid without power failure and dug (3-5)..
