The article points out the drawback of all the current instructions for the lightning protection device: the lack of instructions for calculating the lightning protection zones of an object located on a slope. The methods of applying the current instructions for the lightning protection device when placing an object on a slope are given, based on the assumption that lightning strikes the lightning rods vertically and perpendicular to the slope. The features of the choice of lightning protection characteristics (calculated points of the protected object, calculated heights of lightning rods, methods of constructing lightning protection zones) are described. A method for calculating the lightning protection zones of an object located on a slope is proposed, based on the assumption that lightning strikes lightning rods perpendicular to the slope, in particular, the concept of the axis of a conditional lightning rod shifted on the object plan for calculating lightning protection zones is introduced. The consequences of the application in engineering practice of the methodology for calculating the lightning protection zones of an object located on a slope, based on the assumption that lightning strikes the lightning rods perpendicular to the slope, are indicated. Using a pulse voltage generator, tests were performed on a model of a lightning rod located on a slope in order to determine the direction of lightning strikes-vertical or perpendicular to the slope. It was determined experimentally that the proposed method for calculating the lightning protection zones of an object located on a slope, based on the assumption that lightning strikes lightning rods perpendicular to the slope, should be used in cases where the protected objects are located on slopes with an angle of more than 25°.
