Innovations in the transformer industry for 2019.

It is interesting to make a brief overview of the presented innovations and business developments that took place in 2019. Here are some of them that, in my opinion, are related to the main trends in our industry. трансформатор новинка

Phase Controlled Cooling Transformer

The Chinese company announced that it has developed the world's first 220 kV evaporative-cooled power transformer that uses a new type of non-combustible insulating liquid heat dissipation material - fluorocarbon. This liquid is a kind of low-boiling, non-flammable, environmentally friendly material used to insulate and cool the transformer by changing the gas-liquid phase.

Compact mid-frequency transformer

Researchers at Ecole Polytechnique Federale de Lausanne designed and built a compact mid-frequency transformer rated for 100 kW and operating at 10 kHz. The idea is to increase the flexibility and efficiency of smart grids and DC distribution grids.

Advanced digital transformer

The new version of Siemens' digitally connected transformer - Sensformer - is based on a digital double operation that simulates the behavior of a physical asset in real time. It comes with several useful tools that compare simulated and measured values.

Industry 4.0 at the new transformer plant

Siemens will build its distribution transformer plant in Guangzhou using Industry 4.0 standard. The plant, which is slated to be operational in 2021, will be a model plant that matches an open innovation ecosystem for the widespread use of digital technologies such as digital powerhouse, industrial IoT, smart campus and connected mobility.

Robot for checking power grids

A small remote-controlled robot that can directly operate in power cabinets was first used to maintain a network in China. It is expected that the robot will be used more widely with the aim of gradually replacing part of human operations.

Ultra-low viscosity biodiesel dielectric fluid

Nynas claims that their new NYTRO® BIO 300X fluid, due to its ultra-low viscosity, allows hot spot temperatures to be reduced by up to 10 degrees compared to average mineral oils and about 20 degrees lower than essential liquids. This fluid has tremendous potential for thermal design, optimization and improvement of overload capacity.

While most of the innovations are based on digital technology, we can see that some of them represent quite disruptive innovations based on physics, that is, the physical properties of materials.

 Changes in the field of business events:

  Siemens has announced plans to divest its majority stake in its gas and energy division, which consists of companies involved in traditional power generation, transmission of electricity, oil and gas, and related services. This came shortly after Hitachi acquired ABB's electricity division in a $ 11 billion deal.

   Hyosung Heavy Industries Corporation entered into an agreement with Mitsubishi Electric Power Products Inc. on the acquisition of their transformer plant in Memphis, Tennessee.

   Cleveland-Cliffs Inc. announced that it has entered into a definitive merger agreement with AK Steel Holding Corporation to acquire all issued and outstanding common shares of AK Steel in a $ 1.1 billion deal.

    Pfiffner International AG, a provider of solutions for customers in the power and rolling stock sectors, has acquired the Swiss company Haefely Test AG, which develops, manufactures and markets high voltage test systems and instrumentation for the power and industrial sectors.

    Megger acquired Power Diagnostix, a German company that develops and manufactures high voltage diagnostic equipment and provides diagnostic services for high voltage installations.
