ANALYSIS OF THE STATE OF THE EXTERNAL LIGHTNING PROTECTION SYSTEM FOR OPERATING ENERGY OBJECTS

LPS of of 62305. LPS for these works. Goal. Development of an algorithm for evaluation of the current state LPS for existing power plants and substations. Methodology. Based on the analysis of IEC 62305, three stages of evaluation are proposed: (based on geodetic and electromagnetic method of the configuration of the object and of LPS), (based on the topographic survey method and the electromagnetic method for determining the configuration of the object and components of the LPS) and stage of analysis and development of recommendations. Results. Three stages, which are a basis of analysis of a condition of LPS based on the created algorithm, An example of the analysis LPS condition of the existing substation with a voltage of 35 kV, created according to the specified method, is given. The program report in 3D form illustrates the unprotected parts of the object. Originality. For the first an algorithm for analysis the state of LPS of operating energy facilities according to the IEC 62305 standard has been developed. Practical value. Typical remarks to the existing LPS are formed. The results of the work can be used
