Emergence of failure within a power system is an unwanted situation when certain parts of the network become separated from the other parts unaffected by this failure. Relay protection system has the task of isolating the sections that are faulty. By activating the protection an alarm is sent to the substation and the dispatch centre. Alarms in the dispatch centre come in the short period of time which can confuse the dispatcher and lead him towards making an error. The proper approach and selection of methods for analysing alarms are both very essential for locating the faulty section. There are two well-known methods for analysing failures; one is a method of finger printing and the other a method of hypothesis. The analysed alarms were the ones in the TS 35/10 kV Istok detachment from the rest of the power system. The aim of this paper is to analyse the alarms that have occurred in the dispatch centre during the 35/10 kV Istok detachment by using the finger print method and the method of hypothesis. The results have been found and the cause of section 35/10 kV Istok failure from the rest of the power system. The given results have confirmed the unit and the cause of the TS 35/10 kV Istok detachment from the rest of the power system.
