Main dimensions (mm) kV rms frequency voltage is not less than full-wave lightning impulse voltage kV peak pressure of not less than flashover increase rate (%) Tensile mechanical load (kN) Weight (kg) structural height (H) disc diameter (D) Nominal creepage distance (L) connection type labeled stem wet flashover flashover 1min wet withstand 50% flashover breakdown tolerance test routine test lh electromechanical electromechanical power detection method is not less than the destruction, the distribution voltage method, while having an intuitive, can accurately determine XWP2-160 suspension porcelain insulators, ceramic insulators performance characteristics change, but it needs to take a measurement, high degree of risk potential weakness is that it is limited; insulation resistance were measured in the low pressure side, energy accurately measure the changes in insulation resistance, but the value is not only reflected in the degree of deterioration of the insulator, and is closely related to many other factors, it is also difficult to accurately reflect the state of deterioration of the insulator, and is difficult to directly determine the exact location of inferior value insulator the possibility of a wide range of practical applications alone is not large; pulse current method is based on the principle of corona discharge, less affected by external factors, along with the development of increasingly sophisticated artificial intelligence technology, to identify a solution that is via artificial neural network fuzzy Loss insulator positioning has become possible; it can detect the low pressure side features also provide the conditions for its widespread use. Line detection method using pulsed current operating conditions must first be considered insulators sensor design. Due to their high frequency corona current, weak signal characteristics,
