Power transformer is vital link in the chain of components constituting a power system, the failure of which affects the supply of electric power to the consumers. The transformers are found to be very reliable, but in some power systems of different countries the transformer’s tripping amount are quite high and majority of these accidents have ambient causes. The paper describes types of risk and the probable causes of failure of major equipment-power transformer and power system at all. There are some data of power system’s tripping causes and protective relaying. Also the proposals how to prevent fault or cause of failure are given.
