Protective relay is a device which is activated because of electrical quantity change such as volt and current or physical quantity like thermal degree and oil move and it leads to start other devices and at last break the circuit by circuit breaker . It is used for earth or air feeders in distribution system power plants in different voltage levels. It is used for protection of low or medium voltage engine in industry like power station and oil refinery in order to warranty engine function and its safety such as assurance about overload status. Main protection of transformer means counting (unit) differential protection which is unit protection. With regard to transformer function importance toward continuous electrification , power transformer protection has a great importance. impedance protection is used for protection of transmission, so that it is possible to discover the kilometer area that the error was happened in it. This kind of protection is mentioned as main protection of airlines. borna niroo karan company(Brnika) is the exclusive representative of Ziegler and Sprecher Automation Contrel on buying, selling, consulting services for automation systems and protective relays including protective relays .
