Introduction. Within the framework of European integration of Ukraine, the international Standard IEC 62305 has been harmonized, which provides for a full inspection of lightning protection devices with a frequency of 0.5 – 4 years, which significantly increases the volume of work. Problem. The adopted Standard is stricter than those for which external lightning protection systems (LPS) of power plants and substations, which are objects of critical infrastructure, have been designed. There is no clear algorithm of actions to bring the existing LPS of existing energy facilities of Ukraine in accordance with the requirements of IEC 62305. Due to the need to modernize the existing LPS facilities, there is a need to develop a single algorithm 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: experimental (based on geodetic and electromagnetic method of determining the configuration of the object and components of LPS), calculation (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, are considered in detail. 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 time, 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 to inspection and modernize the LPS energy facilities, as well as buildings and structures of public importance.
