Cigre Cracow 2017



CIGRE Study Committees A2 'Transformers' will hold its annual meeting in Cracow, Poland, on October 1st-6th 2017. Meanwhile, tutorials and technical visit will also be scheduled during the period. This Colloquium will be a great event for engineers, manufacturers, as well as academic researchers all over the world.


Preferential Subjects:
    PS1 - Sound and Vibration Levels for Power Transformers and Shunt Reactors
  • Calculation/estimation of sound and vibration levels, and comparison with measurements (accuracy/repeatability)
  • Modelling for determination of sound and vibration levels, esp. for new/improved designs
  • Solutions for sound level mitigation

  • PS2 – Diagnostics and Reliability of Components
  • Reliability and failure rates for transformer and reactor components
  • Effect of transformer and reactor components on overall reliability
  • Diagnostics for transformer and reactor components, including identification of incipient failure

  • PS3 – Innovative Solutions for Transport and Installation
  • Experience with mobile sub-stations and transformers, including “Wanderer” transformers
  • Experience with site assembly of transformers (disassembly/re-assembly, testing after installation)
  • Experience with other innovative solutions to overcome limits on transport dimensions and mass

The following working groups will be meeting at the colloquium in 2017:
  • JWG A2/D1-51 PD measurements
  • JWG A2/C4-52 HF models
  • WG A2-53 FRA interpretation
  • WG A2-54 Noise
  • WG A2-55 Life extension
  • New WG Installation and commissioning


CIGRE Study Committee A2 is very pleased to welcome experts from around the World to participate in its 33rd colloquium, which is being hosted by the Polish National Committee in the beautiful city of Krakow. Krakow is famous throughout the World for its cultural heritage, and we hope that seminar delegates will be able to take a short break from the busy programme to enjoy some of what Krakow has to offer.
After careful consideration, the Study Committee have chosen three preferential subjects to support our working groups and improve the performance of new and existing transformers.
Preferential subject 1 will be “Sound and Vibration Levels for Power Transformers and Shunt Reactors”. This subject is being studied by working group A2-54, and experts from inside and outside the outside the working group are encouraged to contribute. It will include calculation and estimation methods for sound and vibration levels, together with comparison with measurement results from actual power transformers and shunt reactors. Consideration can be given to accuracy of calculation and estimation method, and also to repeatability of measurement results. It will also include use of advanced modelling techniques, especially for development of new designs. Finally, the preferential subject will include sound level mitigation methods, for both new and existing power transformers and shunt reactors.
Preferential subject 2 will be “Diagnostics and Reliability of Components”. In recent years, the study committee has given detailed consideration to the reliability of transformers as a whole and also transformer bushings. This preferential subject is intend to build on this earlier work, and will include consideration of reliability for transformers as a whole and for individual transformer components; the effect of component reliability on overall transformer reliability; and diagnostic methods for individual components, including identification of incipient failure.
Preferential subject 3 will be “Innovative Solutions for Transport and Installation”. Transformers users in many countries are looking for innovative solutions to transport larger transformers from works to site, using existing transport infrastructure. This preferential subject will include experience with mobile substations and transformers, both for road and rail transport (so-called Wanderer transformers). This subject will also include the fast-developing area of site assembly of transformers. Experts are also encouraged to submit papers on other innovative solutions for transport and installation to overcome limits on dimensions and mass.

Technical visit

Pumped Storage Power Plant Porabka Zar

The EW Porabka-Zar pumped-storage power plant was placed in operation in 1979, and was then a showpiece facility in terms of the hydro power sector's engineering achievements. It was built in the period of dynamic development and expansion of the Polish power sector. With a capacity of 500 MW, it is the second largest pumped-storage power plant in Poland, located in Miedzybrodzie Zywieckie, in the vicinity of the Beskid Zywiecki Mountains. The facility boasts advanced technological solutions, ability to promptly react to load changes in the power grid, and high availability reaching 94%. The power plant's design makes it quite unique. It is an underground facility, the only one in Poland, and an interesting feat of engineering in Europe.
