Abstract

The valuation of the risk of losses makes easy the correct estimation of resulted threats as a result of atmospheric discharges and harms connected to them. Qualifying the need of lightning protection use for the object, we ought to take into account the risk R for the object and for the public services devices. In every case of examining risks we ought to fulfill: the identification of components RX forming the risk, counting the identified components of the risk RX, the entire risk R, identify the tolerated risk RT and compare the risk R with the tolerated value RT. As a result of such analysis we can come to a decision about the use of protection resources. In the report was realized the risk analysis of devices damages for a chosen object - the signal box with installed station - relaying devices of the railway traffic controlling with a computer adjustable control panel. From the realized analysis results that DEHN Risk Tool is a useful tool for the risk analysis of lightning losses in buildings, making possible the improvement of the calculations process, especially in the range of the choice of proper protection resources.
