- Abstract
Power transformers are used to change the level of voltage in power systems. Power transformers increase the voltage level of electrical energy in production plants and transfer them to the transmission system. The transmission voltage in Turkey is generally 380/154 kV. The voltage at this level is reduced to a voltage of about 34.5 kV at the power down-center. Power transformers are the most expensive and important equipment among the power system. Therefore it is important to protect the power transformers from various malfunctions in the power system or from faults occurring in it. While this process is accomplished with various protection relays, the differential protection relays are usually used. In this study, the protection coordination relay analysis of a power transformer of 154/34.5 kV was done by modelling a protection relay with basic characteristics. The DigSilent power systems analysis software was used to model the power system and simulate the basic differential protection relay.
