Power Transformer Protection

The Power Transformer Protection 4 hour PDH online course is a part of the Electrical category courses.

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 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 suitable for electrical engineers with a desire to understand the power transformers protection fundamentals. Presented details include details related to interturn, tank and core faults. Information on over-voltages, magnetizing inrush, overheating is also included. Upon successful completion engineers will be able to address the most important power transformer protection aspects, widely adopted protection schemes and arrangements and their proper application.
