The contribution describes probabilistic approach for evaluation of earthing system safety, which can complement the conventional earthing design methodology given by standard EN 50522, similarly as mentioned in British Annex NA. The main part of the contribution is application of the probabilistic risk assessment approach on case study of distribution transformer station earthing system. For presentation of benefits of probabilistic approach, the system solidly earthed, isolated, resonant earthed and resistor earthed were respected as the part of the case study. The contribution stipulates all crucial aspects of this process including probable drawbacks flowing from high amount of non-well known input variables which are necessary for probability calculation, e.g. human body presence, respected risk scenarios, frequency and type of earth faults, fault/contact coincidence, etc. The last part of the contribution is focused on sensitivity analysis of all crucial input variables which can affect final individual risk probability.
