The insulator strings of Extra High Voltage (EHV) and Ultra High Voltage (UHV) transmission lines are longer. It is more convenient and effective to detect insulators with robot. Currently, insulator detection robots mainly work by climbing along the insulator string, the structure is bulky and complex, and needs further improvement. Therefore, this paper proposes a split insulator detection robot which is suitable for the detection of suspended insulator string. The electric field distribution around the insulator robot is simulated and analyzed. The test experiment of 220 kV insulator string is carried out. The results indicate that the maximum electric field strength around the split type robot is 1753 kV/m. Partial discharge will not be generated. The measured potential value of the insulator detection robot is less than the original voltage distribution value of the insulator. The actual voltage distribution of insulators can be obtained by compensation and correction, then the detection of low and zero insulators is carried out.
