The advancement of electrical power systems has been reflected in the developments in power transformer manufacturing. This has led to a wide range of power transformers. Their ratings range from a few kVA to several hundred MVA and they are used for a wide variety of applications.
Power transformer protection varies with the application and transformer importance. In the case of a fault within the power transformer it is important to minimize tripping time in order to decrease the impact of thermal stress and electro-dynamic forces. Distribution power transformers can be protected by using fuses or overcurrent protection relays. This leads to time-delayed protection due to downstream co-ordination requirements. Nevertheless, time delayed short circuit clearance is unacceptable on larger power transformers due to system operation/stability and cost of repair.
This course is intended for electrical engineers with a desire to understand power transformers protection fundamentals. Presented information includes details related to interturn, tank and core faults. Information on over-voltages, magnetizing inrush, overheating is also included.
