A challenging problem in the protection of power transformers is the fault detection and
diagnosis (FDD). FDD has an essential role in the reliability and safety of modern power …

This contribution is aimed at obtaining diagnosis criteria for detection of low-level short
circuit faults throughout sweep frequency response analysis (SFRA) measurements on the …

This paper presents a general approach to compute the leakage inductances of power
transformers with turn-to-turn winding faults. The leakage inductances are obtained by using …

Frequency response analysis (FRA) is gaining global popularity in detecting power
transformer winding and core deformations due to the development of FRA test equipment …

This paper presents an approach based on the use of transformer no-load and light load
current harmonic analysis to detect the presence of an interturn fault at the incipient stage …

Power transformers are of the most critical and expensive equipment in the power system
industry. Meanwhile, they are exposed to a variety of faulty and abnormal operating …

In this paper, a new technique for low-severity inter-turn fault detection under online
operating conditions of dry-type transformers is proposed. The proposed methodology …

Converter transformer inter‐tap short‐circuit faults in on‐load tap changers have occurred
successively in recent years, resulting in severe accidents and enormous losses. Due to the …

Turn-to-turn short circuits occur due to insulation damage in transformer windings and these
may potentially result in catastrophic faults affecting electric networks. In fact, transformer …

Interturn short-circuit faults are the leading cause of power transformer's failure. If not
detected at the incipient stage, these faults usually develop into more severe faults that …
