Historical Development of the Transformer

8th Mediterranean Conference on Power Generation, Transmission, Distribution and Energy Conversion (MEDPOWER), 2012

This paper analyzes the bibliography on transformer research covering the period of 2001-2010. Due to the large number of publications in peer review journals, conferences and symposia contributions were not included. That is why 22 peer review journals were investigated, in which 933 papers including the word “transformer” in their title have been published in the decade 2001-2010. The most productive and high-impact authors and countries are identified. The four most productive countries are Japan, USA, China, and Canada. More than 75 citations were received by each one of the five most cited papers. The bibliographic research presented in this paper is important because it includes and analyzes the best research papers on transformers coming from many countries all over the world and published in top rated scientific electrical engineering journals.

Electrical and Electronic Engineering, 2012

This paper presents an analysis of the bibliography on transformers covering the period from 1990 to 2000. It contains all the transformer subjects: a) Transformer design, b) Transformer protection, c) Transformer connections, d) Transformer diagnostics, e) Transformer failures, f) Transient analysis of transformers (overvoltages, overcurrents), g) Modeling and analysis of transformer using FEM (thermal modeling, losses modeling, insulation modeling, windings modeling). Several international journals were investigated including the following: Advances in Electrical and Computer Engineering, Canadian Journal of Electrical and Computer Engineering, COMPEL (The International Journal for Computation and Mathematics in Electrical and Electronic Engineering), Electrical Engineering, Electric Power Components and Systems, Electric Power Systems Research, European Transactions on Electrical Power, IEEE Transactions on Magnetics, IEEE Transactions on Power Delivery, International Journal of Electrical Power and Energy Systems, and IET Generation Transmission & Distribution. Due to the high number of publication in journals, we are not considering publications of conferences and symposia. A total of 700 publications are analyzed in this paper. The research presented in this paper is important because it contains and analyzes the best research papers on transformers coming from many countries all over the world and published in top rated scientific electrical engineering journals.

Archeologia Postmedievale, 2020

The Artillery of the Venetian Public Ship Croce Rossa (1698- 1715). An Archaeological and Archival Study. The so-called “Cannon Shipwreck” was discovered in 2003 near the entry to the port of Malamocco in front of Venice. In 2005 and 2006 it was the subject of two archaeological campaigns. Through archival research it was possible to identify it as the Croce Rossa (1698-1715) a first rank Venetian vessel which had sunk at the entry to the harbor during a storm. In this paper we have dealt with the documentary and archaeological aspects of the artillery mounted on the Croce Rossa during the period when it was in operation. This research demonstrated that at the time it was launched and during the first War of Morea in which it participated, the ship was equipped with sixty-eight bronze and iron cannons including the ingenious “new discovery” heavy artillery invented by Sigismondo Alberghetti. As part of the weaponry there were also twelve bronze 6 venetian “libbre sottili” swivel guns. At the time of the sinking which occurred in November of 1715, due to the poor condition of the hull, there were only thirty-nine cannons left on board, most of which were recovered after the sinking. During the archaeological excavation four iron cannons were found, two of which were recovered and restored. Both of these cannons were of English manufacture. The first was identified as a demi culverin 9 pounder (14 Venetian libbre sottili) which had originally been produced for the English State, while the second one is a 20 venetian “libbre sottili” made by the British foundry of Thomas Western for the Venetians. In fact, it is marked with the “leon in moleca” in relief which meant that it was the property of the Venetian Republic.
