Study and simulation of electrical transformer protection using (differential protection)
Abstract
Abstract: The continuity of electric energy and its availability provision at an appropriate price is a measure of the country’s progress, and the electric power system, which consists of generation units and networks for the transmission and distribution of electric power, requires enormous efforts and large and diverse equipment in order to deliver the electric current to the consumer in a correct and continuous manner. The electrical power system, including its components, such as generators, transformers, overhead transmission lines, and cables for transmitting and distributing electrical power, is exposed to some malfunctions that may cause the system to stop working due to a malfunction or damage to one of the elements of this system and consequently a power outage if the necessary preventive measures are not taken, and accordingly This paper presents a study on the differential protection of electrical transformers This is due to the importance of transformers in raising and lowering the voltage in the electrical power system and transferring power over very long distances from its generation sites to its utilization sites. where has been made Conducting of a simulation through the work of transformers and the causes that lead to malfunctions in these transformers, to arrive at the appropriate protection method for these transformers based on the study of the problems that caused these malfunctions.
