This paper shows possible options in protection of power lines by digital relays, that are used in Slovak power system. It shows demands given by STN and possible protection schemes. Electric power lines are still the only media for electric power transportation from power plants to customers and they can be, notwithstanding thoroughgoing operating, liable to various mechanical or electrical failures. Relays can not prevent failures, they just minimize their consequences. This paper shows just a part of power lines protection area, aimed for protection schemes and relays used in Slovak power system. Big systems outages that last year affects power systems in Italy and United States shows, that question of protection coordination and correct choose of protection scheme are significant demands for trouble free operating of power systems.
