Tutorial on Protection of Three Single-Phase Transformers
2019 72nd Conference for Protective Relay Engineers (CPRE), 2019At the design stage of a new power substation, one of the decisions to be made is whether to select a single three-phase power transformer or a bank of three single-phase transformers. At Churchill Falls Terminal Station 2, of the Lower Churchill Project, a bank of three single-phase 3×280 MVA 735 kV power transformers was selected because of the ...

On the Effects of Subsynchronous Interharmonic Voltages on Power Transformers: Single Phase Units
IEEE Transactions on Power Delivery, 2008The effects of subsynchronous interharmonic voltages (SIVs) on three phase power transformers are presented and discussed. In a companion paper, the results of an experiment study a single phase transformer highlighted the need for accurate modeling of the magnetization curve.

Feasibility of distributing electric power through single-phase transformers at rural regions of Turkey based on rural characteristic indices [PDF]
, 2017 Single-phase (1-phase) transformers have been utilized in some countries to supply rural distribution regions which particularly have relatively low load densities (farms, villages, etc.).

Single-phase insulator transformers
IEEE Potentials, 2002To show that voltage surges are effectively transmitted between the windings of insulator transformers, a relatively simple and functional test was prepared. The test applied differential-mode voltage surges with small amplitudes to the primary winding of three different types of single-phase no-load insulator transformers.

Notes on parameter estimation for single-phase transformer
IEEE Transactions on Industry Applications, 2020This article investigates the inaccuracies of identifying parameters for a single-phase transformer. In addition, in this article, two new transformer parameter estimation algorithms based on recently developed optimization techniques, as well as an objective function, are proposed for the transformer parameter estimation to improve the estimation ...
