The distribution of the power transformers at a far distance from the electrical plants
represents the main challenge against the diagnosis of the transformer status. This paper …

Transformer oil insulation condition may be deteriorated due to electrical and thermal faults,
which may lead to transformer failure and system outage. In this regard, the first part of this …

Power transformers are considered one of the power system's most critical and expensive
assets. In this regard, it is vital to assess the fault within the power transformer considering …

The early detection of the transformer faults with high accuracy rates guarantees the
continuous operation of the power system networks. Dissolved gas analysis (DGA) is a …

Power transformer represents an important equipment in electric power systems.
Transformers are not only a source of power outages for electric utilities, but they also affect …

The prediction of fault type in transformers at an early stage is an important aspect for power
system reliability. Checking the transformer status begins with the dissolved gas analysis …

Improving the accuracy of transformer dissolved gas analysis is always an important
demand for power companies. However, the requirement for large numbers of fault samples …
