Nowadays, various fields are in the process of modernization and the demand for electricity is high, which also puts forward higher requirements for power technology. The short-circuit protection technology is one of the more representative and highly applied technologies in the field of electric power, which can play a key protective role for the relay protection power system, which is also an important prerequisite for the stable and reliable operation of the relay protection power system. Based on this, the short-circuit causes of the system are analyzed in depth, and the actual analysis finds that user-side faults, insulator faults, and three-phase system faults are the main causes of short-circuit,and several key technologies for short-circuit protection and corrective measures are proposed for the above problems,which can hopefully help to guarantee the normal operation of relay protection power system.
