Transformers Magazine Vol. 7 Issue 1
Dear readers, As I write this text at the very end of the year, it is interesting to make a short review of the innovation presented and business events that have happened in 2019. Here are a few that in my opinion are related to the main trends in our industry. The innovations are as follows: Phase-change cooling transformer A Chinese company announced that they… 
You represent a company from Poland that, in the last several years, has been successfully gaining a foothold in the international market. What is your business philosophy? Our philosophy is based largely on the fact that we want to solve problems with our clients face to face. We are not a corporation with many anonymous people, where clients are just a revenue-generating record in a… 
Transformers and the energy system transition Having spent most of my career in the engineering and asset management of transformers working for National Grid in the UK, I have taken the opportunity of moving into the academic world as a professor at the University of Manchester. National Grid gave me fantastic opportunities to work with transformer manufacturers and see many transformer factories around the world.… 
Transformers vibration and noise reduction In recent years, with the continuous expansion of power network transformation and urban construction, it is becoming increasingly common for small and medium-sized transformers to be installed in residential or commercial areas and other application scenarios, which brings with it transformer noise pollution to nearby residents and affects their lives in the process. Therefore, vibration and noise reduction has become… 
University Transformer Research Alliance Discovery of the electromagnetic induction principle by Michael Faraday in 1831 laid the foundation for design and development of transformers. Work carried out at the Ganz factory in the early 1880s in developing the closed core transformers is considered as the pioneering work in development of the modern transformer. Since then, the design, development, operation and management of transformers have been… 
A century of dissolved gas analysis - Part III Introduction With time, the size of the transformer increased exponentially both in power and voltage. Although huge improvements have been made regarding the magnetic core and the decrease of core losses, a transformer is now producing much more heat due to the design optimization and size reduction. Heat reduces the insulating properties of the insulating matrix,… 
L.A.E. keeps on leading the core cutting lines innovation L.A.E., Lughese Attrezzature per l’Elettromeccanica, has been leading the core cutting lines innovation for years, being the first company to design and install anthropomorphic robots for the automatic core stacking and devices for the fast replacement of the lamination on the decoiler (FRS). The Italian company has always been devoted to innovation, while keeping the connection… 
Transformer innovation in a changing energy landscape – Part I Abstract We are in a changing energy landscape, transitioning to the future of energy on waves of innovation that respond to the economic, demographic, and environmental challenges of today. Electricity is becoming an important contributor to the energy transition in a connected and data driven society with rising electrical mobility. The future of energy will… 
Shunt reactors improve voltage stability and power quality ABB’s leading position in high and ultrahigh-voltage shunt reactors stems from an uncompromising commitment to quality, innovation and technical excellence. ABB shunt reactors provide innovative technology to meet the needs for voltage stability, power quality and integration of renewable energy. The networks for transmitting and distributing electrical energy face new demands due to changes in power generation… 
ABB’s transformers for special applications meet special needs Designed to be flexible, compact, and adaptable, ABB’s specialized transformers are available in a broad range of voltage levels and power ratings; units for subsea or mobile substations and data centers operate with reduced losses. For complex applications or harsh conditions standard transformer products might not be feasible. Drawing on 100 years of experience and a global… 
Transformers to power Indian Railways Indian Railways has ambitious electrification targets and has found that ABB’s comprehensive range of transformers provides an ideal and eco-efficient means not only to power trains, trackside and stations but also to boost rolling stock speed and performance. With approximately 200,000 employees and a rail network that encompasses over 64,000 km of routes, Indian Railways is one of the biggest… 
Power fulfilment with ABB’s UHVDC and UHVAC transformers By enabling high transmission voltages, large amounts of electric power can be transmitted over great distances at high efficiency. ABB has made ground-breaking developments in UHVDC and UHVAC transmission; today 1,100 kV DC and 1,200 kV AC is possible. Energy demands are growing and a 70 percent increase in electricity consumption is anticipated by 2040, with… 
Mapping transformer populations Abstract This article introduces a model for mapping transformer populations. The concept of mapping goes beyond a transformer condition assessment to include the financial risks of power disruption and downtime. Different power plant types or industrial production facilities can experience significant cost increases due to production downtimes from the loss of all or a part of the transformer population. Even a single… 
Exploring multifunctional in the realm of transformer diagnostics Acquiring diagnostic insight into the condition of an asset through testing has several dimensions. Foremost, testing must be safe. Having diagnostic information should deliver positive net value when weighed against the cost of its acquisition. A test instrument must effectively overcome measuring complexities that are inherent by-products of a live power system test environment and must consistently… 
Detection of winding inter-turn faults – Part I Abstract This article deals with inter-turn fault detection in the transformer winding, inter-turn fault which occurs due to insulation degradation between one or more sequential turns of the winding. If the fault is not detected at the earliest stage, it propagates to the nearby turns of the winding during certain period of time and it causes irreversible… 
Corrosion protection of core steel in dry-type transformers Abstract This article demonstrates how corrosion of core steel starts, presents its negative effect on transformer’s efficiency, talks about the types of coating used on core steel material as well as the methods used in applying those layers of coating. It also provides a collection of data and best practices useful to identify the proper method for… 
The transformation of transformers Abstract From Michael Faraday’s observation of electromagnetic induction in 1831 through today’s largest standard, converter and industrial power transformers, this article summarizes the major steps realized in the development of transformers since the beginning. It also showcases how GE Renewable Energy’s Grid Solutions’ ancestor companies such as DELLE, British Electric, Thomson-Houston, GEC Alsthom, AEG to name few of them, played a… 
Renewable energy rises to the top of Middle East’s energy agenda Middle East electricity demand to triple by 2050 More than $100 B worth of clean energy projects already in pipeline Cost of installing photovoltaic solar in Middle East has fallen by 73 % since 2010 The Middle East’s energy and utilities sector is undergoing an unprecedented transformation, with the shift towards renewable energy and… 
ComEd and IEEE Host PES T&D Conference 2020 We need clean energy and electrified transportation, but how will the grid integrate them? As stakeholders recognize the need for advanced technologies to allow their communities to benefit from clean power, leveraging these innovations requires additional grid capabilities. In April, the largest gathering of utility professionals and energy researchers in the world will be in Chicago…
