Transformers & Transmission Conference

12th – 13th March 2019
London, United Kingdom



“Global power transformer market size is expected to reach $35,353 million by 2022 from $23,019 million in 2015 with a CAGR of 7.07% from 2016 to 2022.”

“The power transformer market in LAMEA accounted for $1,608 million in 2014 and is anticipated to garner $2,816 million in 2022 expanding at a CAGR of 7.20% between 2016 and 2022.”

About the Event

TThe global transformers market is likely to grow at a significant rate, owing to augmentation in power infrastructure promulgated by surge in demand for electricity. The prominent drivers supporting the growth of global power transformer market are rise in transmission and distribution infrastructure investments and growth in the renewable energy sector.

The global power transformer market is expected to grow and register a CAGR of 8.65% next few years, from key regions North America, Europe, Asia-Pacific, Central & South America, Middle East and Africa.

However, with the development of Chinese domestic Transformer industry, the performance distance will shorten gradually, compared with the imported Transformer. Currently, the Chinese Transformer industry tries to transit to high-end Transformer field actively, as well as extends downstream industry chain.

Analyzing the Causes and Effects of Overvoltage in Transformer

In addition to their normal operating voltages, transformers are subjected to occasional over-voltages arising during transient events on the system, e.g. lightning strikes or switching, and these can cause failures and so transformers must be designed and tested to ensure they can be withstood. This presentation will discuss the effects of external over-voltages and internal over-voltages generated by internal resonances, in-rush and over-fluxing, and how these are accommodated.

Advanced Thermal-Hydraulic Modelling Techniques Power Transformers


Temperature is one of the limiting factors in the application of power transformers. According to standards, a temperature increase of 6°C doubles the insulation ageing rate, reducing the expected lifetime of the device. Power losses of the transformer behave as a heating source, and the insulating liquids act as a coolant circulating through the windings and dissipating heat. For these reasons, thermal modelling becomes an important fact of transformer design, and both manufacturers and utilities consider it. 

  • Different techniques for transformer thermal modelling
  • Predicting the hot-spot temperature in the transformer windings with good accuracy.
  • Using different models  in scenarios of emergency load
  • Widely acclaimed methods – CFD vs THNM

Day 2: 13th March 2019
Natural Ester Fluid in Large Transmission Transformers: Tamini’s Experience


Vegetable-base liquids have been developed as an environmentally-friendly alternative to the mineral oil. Up to some years ago, the use of these liquids was restricted to low voltage small power applications. In the last decade, high voltage large power transformers using vegetable-base liquids have been manufactured and put into operation.

  • Transformer design and manufacturing with ester oils
  • Life expectation and capability
  • Environment and safety

Reliable Evaluation of Paper Insulation in Transformer


It is often stated that the life of a transformer is determined by the ageing of the paper insulation, and this is because the likelihood of an end of life turn to turn failure under over-voltage or short circuit events depend on the state of the insulation. Unfortunately, although assessment techniques have been developed to determine transformer condition in various aspects, the evaluation of the aged state of the winding insulation is the most problematic. This presentation will discuss the ageing process in paper insulation and how this can be reliably evaluated by dissolved gas results, oil analysis and paper sampling, with case examples to illustrate practical difficulties.

John Lapworth, Senior Principal Engineer, Doble Engineering Company

Latest on Natural and Synthetic Ester Fluids


A newer approach to risk management gaining worldwide momentum is to employ ester-based fluids in both distribution and transmission transformers.  Ester fluids have a number of advantages over mineral oil; they have higher fire points and lower gas conversion factors, reducing the risk of tank rupture and allowing installation closer to the load centre.  This can be especially useful in distribution networks where transformers need to be located close to, or inside, buildings.  For larger transmission transformers, using a high fire point ester potentially allows significant reductions in fire protection, which can lower the overall installation cost of a substation, particularly in constrained urban locations.  In addition, ester fluids are more environmentally friendly, offering reduced risk in the event of a spillage or leakage.

Inspections and Transformer Scrapping- Investigating Copper Sulfide Contamination


Deposition of conductive copper sulfide on paper insulation of power transformers has been a real and significant issue for a large power transformer. In some cases, has resulted in expensive equipment failure. It has been said that sealed equipment, containing sulphurous oils and operating at elevated temperatures, are the more susceptible to the copper sulphide deposits. Combination of factors such as time, temperature and Oil oxidation can increase deposition of Cu2S on the insulating paper, that may cause voltage stress and a subsequent burn through (failure)
