Transformers are one of the essential components of power systems. If, for any reason, these transformers are out of service, irreparable losses due to non-continuous power transmission are introduced to power system operators, and the reliability of the power grid is reduced. Significant costs incurred annually by operators for the maintenance and repair of transformers are just one of the factors driving the condition monitoring of transformers. Power transformer condition monitoring is the first step in improving the performance of transformer and increasing the efficiency of maintenance and repair processes.

Transformers condition monitoring and obtained data analysis provide engineers with all the technical information needed for fault detection and repair process. Accurate monitoring of transformer parameters enables the equipment to be operated correctly and thereby increase the life span of the transformers, while also benefiting from the savings caused by the repair elimination. The correct operation of transformers plays an essential and effective role in maintaining grid stability and improving grid reliability.

Nevertheless, several factors such as improper operation and failure to perform periodic service and repairs can cause critical conditions for the transformer. These critical conditions not only reduce the life of the transformer, but also impose high repair and transformer elements replacement costs, and sometimes it even causes the transformers to get out of the circuit, which then limits the transmission of electricity to the grid. Power Transformer Condition Monitoring and Diagnosis is essential reading for researchers in academia and industry involved with power transformer R&D, engineers in utilities working with equipment monitoring techniques, and advanced students in power engineering.
