Abstract The distribution transformer is the mainstay of the power system. Its internal temperature study is desirable for
its safe operation in the power system. The purpose of the present study is to determine direct comprehensive
thermal distribution in the distribution transformers for different loading conditions. To achieve this goal, the
temperature distribution in the oil, core, and windings are studied at each loading. An experimental study is
performed with a 10/0.38 kV, 10 kVA oil–immersed transformer equipped with forty–two PT100 sensors (PTs)
for temperature measurement installed inside during its manufacturing process. All possible locations for the
hottest spot temperature (HST)… More >
