Применение методов неразрушающего контроля качества при обследовании состояния систем молниезащиты пожаро-взрывоопасных объектов
The issues of non-destructive testing carried out during the inspection of the state of lightning protection systems for fire and explosion hazardous facilities, are considered. Including the objects of the main oil and oil product pipelines were considered. It is indicated three types of tests have to be used: quantitative assessment of the necessary elements of the lightning protection system, visual and measuring control of the system elements using geometric and geodetic measurements, and measuring the electrical parameters of the elements of the lightning protection system. The features of control and measurements related to the calculation of protection zones against a direct lightning strike when using lightning rods of various types or their combinations are described. Examples of the estimation of the error in calculating the protection zones against a direct lightning strike are given.
