Dear readers,
The recent surge in global commodity prices is probably the most discussed business topic at the moment. In several instances, raw material prices have doubled over the past year. Clearly, this has created great challenges for the sustainable manufacturing business and caused some transformer manufacturers to publicly announce price increases. Transformers Magazine has previously published educational materials on supply chain management and I would like to take this opportunity to jog your memory about the articles written by Ufuk Kivrak – ‘Creating value through supplier relations management and strategic partnerships’, published in volume 7 (2020), issue 4, and ‘Supply chain management’, published in the Special Edition on Substations in 2019, in which you can find very useful recommendations on how to reduce the risks of rising raw material prices.
In this regard, I would like to draw your attention to the highly topical research on technology and market trends that is currently conducted by Transformers Magazine. Additional information about the research is available on our website, so please feel free to contact us in case you have any questions about it.
An innovative range of 3D moulded insulation parts
These products offer OEM´s and end customers vast grades of freedom for designing advanced temperature transformers according to IEC 60076-14 (transformer standard).
Timing and modality to obtain representative and beneficial DGA sample for liquid-filled device
For Transformers Magazine readers, the importance of DGA to transformer health and transformer owner’s reputation does not have to be described or promoted.
Peter Schikarski – CEO at Haefely AG
The highlight of the 2019 interview was transformer testing, in the new environment that Haefely acquired within the Swiss Pfiffner Group.
Sharing our expertise with remote services to achieve sustainable performance
The risk of sudden transformer failure entails not only huge replacement costs and downtime but is also hazardous to the environment and human life.
Enhancing the reliability of offshore wind farm transformers with customized design and maintenance
Many nations have set goals to meet a significant proportion of their energy needs from non-conventional sources.
Standards relevant to transformers – Part VI
Transformer specification is a “common language” between manufacturers, suppliers, vendors, engineers, or any other parties that work with transformers on the technical level.
Peter Grolmus – CTO at Ekofluid GmbH
Most oil treatment equipment on the market is still being build the same way it was built twenty or even forty years ago.
MR TAPCON® 230

This is in continuation of the bibliography of books on power transformers in the German language published earlier [1].
The Power Diagnostix by Megger ICMmonitor: A versatile device for on-line or temporary partial discharge monitoring of power transformers
Keeping the power on, the mission of Power Diagnostix (PDIX), is vital to the success of any power grid operator.
Deviation of short-circuit impedance from specified design value
The mass production of transformers has led to the use of standard methods for controlling technological processes in a series production environment.
Investigating cost-benefit analysis for digital distribution transformers – Part I
Due to the changing dynamics and increasing complexity of today’s electricity grid, the need for dynamic asset management strategies is very evident.
Importance of using high test voltage for transformer turns ratio test
The transformer turns ratio test is one of the fundamental transformer routine tests declared by both IEC 60076-1 and IEEE C57.12.90. standards.
Optical sensor for determining the degree of polymerization of the insulation paper inside transformers
Performance is depending on the degree of polymerization of cellulose, which is the average number of monomeric units (glucose rings) in the cellulose chain.
Digital transformation as a backbone for holistic product development of transformers
Digital transformation has become a buzz word and the technology is facing a challenge in implementation when attempting to reap the benefits of digitisation.
