Transformers Magazine Vol. 6 Issue 2
Dear Readers, If you examine closely the topics we will discuss in this issue, you will find many themes ranging from rural areas electrification projects to megacities. Megacities and rural areas are two extreme cases for transformers. Rural areas, which are usually vast and scarcely populated, have simpler technical requirements, however, the building of needed infrastructure is harder to finance. Densely populated urban areas, where… 
TRANSFORM platform TRANSFORM was established in 1998 by MR as a platform for premium European manufacturers and suppliers to the transformer industry. The idea was that by providing first class, premium components for transformers, you end up with high quality, very reliable transformers. TRANSFORM was intended as a platform where premium suppliers to the transformer industry can talk to their customers - transformer OEMs, grid… 
Expedite your transformer testing process Power transformers are widely considered to be the most critical components in electrical transmission and distribution networks. Due to the aging of transformer fleets in the field, regular diagnostic testing and condition assessment become increasingly relevant. Transformer designs can be very complex and, thus, measuring the variety of different parameters can be a time- and cost-intensive job. In order… 
Sic Transit Gloria Dux The beginning In the third quarter of 1987 simultaneous announcements in Sweden and Switzerland made public the news that an agreement had been concluded which would see the merger of Asea AB and BBC Brown Boveri Ltd to form the new company ABB. Headquartered in Zurich, Switzerland each parent company held 50 percent of the new company and operations began on… 
Carlos Jacomini has been in transformer insulation business for nearly 25 years. His background is mechanical engineering. He started in ABB Brazil in 1996, and then in 2000 he moved to Siemens Brazil. He also spent 1.5 years in Siemens in Germany. His responsibilities included optimization of insulation system and development of the concept of insulation kits in Brazil. In 2004 he started Isoletri, a… 
SensgearTM & Sensformer® advanced: Born connected 2.0 Digitalization is a chance and an enabler. It empowers industries to tackle their current challenges like performance increase, health, safety & environmental topics, cost and risk reductions. However, to benefit from digitalization it is necessary to generate data in the first place. While these opportunities seem to be common sense in many industries already, the transmission and distribution…

Don founded and ran a successful electrical sales agency in Houston, Texas, while remaining active in his family’s privately held business, VanTran Industries, Inc., located in Waco, Texas. He held the position of CFO at VanTran from 2011 – 2016 and served on the Board… 
Reliable quality Oxyweld is a leading Italian manufacturer of oxyhydrogen gas generators for brazing. With its Oweld brand marking its 38th anniversary and thanks to its experience and global presence, today the company supports many transformer producers and repairers in more than 70 countries, including the main players. Oxyweld’s brazing technologies turn distilled water into gas and replace the conventional oxy-fuel cylinders (i.e. the most… 
Situational awareness brought to you by IoT Increased technology, such as the Internet of Things (IoT), does not increase situation awareness itself. However, technology will help reduce the impact of the situational awareness barriers and improve decision making when used as it was intended [1]. We can become mesmerized by technology that can be held in our hands to communicate, learn, and entertain to… 
Ken Gao has been working in the transformer insulation industry for more than 15 years. He joined Weidmann in 2012 as an account manager with a focus on the distribution transformers market in China. He has an MBA degree from Shanghai University of Finance and Economics. Combining materials and technology for high-quality and high-efficiency transformers As the world leading supplier of insulation technology for key… 
Monitoring demanding and long-distance transports Continuous monitoring during transport Transport damage is an often-cited cause of product problems. The repercussions of damages to your product are not only related to immediate cost of repairs, replacements, and delays, but also to premature failure during the component’s lifetime, extra service costs, loss of productivity and damage to the company’s reputation. Therefore, it is important to determine… 
Commodity risk management in transformer industry Introduction Transformer manufacturing includes a number of raw materials, which show significant price fluctuation and therefore represent a major risk for transformer producers. During 2004-2008, when commodity prices exploded globally, many producers have had huge losses due to lack of understanding of the risk management methodology and wishful thinking. Some of the raw materials used for transformers are… 
Detection of open phase condition in power transformers Abstract This article deals with open phase events in power transformers, mainly related to nuclear power plants where several cases have led to a global initiative for a prompt solution for this vulnerability. Different solutions are possible, and one of them, which has already been tested at a Spanish nuclear power plant, is presented here. Field… 
Innovative solutions for distribution transformer cores and windings Abstract Focusing on the real needs of the transformer core manufacturing process, the first step is to improve existing solutions and find new, innovative solutions at a whole process level, with the aim to produce highly efficient transformer cores in a both productive and competitive way. The first innovative improvement concerns the automation of the stacking… 
A dry type HV insulation system for extreme environments Abstract The aim of this article is to make readers aware of a dry type, paperless insulation technology that offers a safer and cost-effective alternative to traditional oil-filled current transformers. The design concepts and advantages of this unique HV dry type current transformer technology have been delivering verifiable improvements to the power grid over the… 
Expanding the diagnostic impact of power factor testing Abstract The Narrow Band Dielectric Frequency Response (NBDFR) test method consists of a series of power factor measurements ranging from 1 to 1000 Hz. This aggregate of the CHL (primary to secondary) measurements constitutes the dielectric response of the test specimen. The subsequent evaluation consists of a geometric analysis of a plot where the measured power… 
MY TRANSFO 2018 (www.mytransfo.com) was the ninth edition of the conference focused on transformers and transformer oil. This 2-day conference, held in Turin, Italy, December 18th -19th 2018, gathered 185 participants from 27 countries. 99 companies were represented. 26 speakers, through the presentations and two round-table discussions, provided a lot of valuable content for the audience.
