To avoid such interference, a protection system is needed, one of which uses differential relay. This differential relay works very fast and does not require time delay by detecting the difference in the current entering the stator coil, if the current is different then the differential relay will work. The purpose of this study was to analyze the differential relay settings on generators at PT PJB UBJ O&M Rembang PLTU which affect the reliability of the generator. The method used in this study is a quantitative method, where in this method a research approach is widely demanded to use numbers from data collection, processing of data, and appearance of the results. The results obtained from this study suit the differency of 0.1804 A, which means it is still in good condition, so it can carry out its duties as a protection system at PT PJB UBJ O & M Rembang PLTU} }
