A. Eberle MULTIAPP app for iPhone and iPad

With this APP you have a complete and up to date reference work on the principles of electronics technology for the measurement of power and total ratings in three-phase systems. It focuses on and discusses measurements and measuring instruments, the acquisition of measurement data, measurements in energy technology, power ratings in three-phase systems, operational factors in power measurements and total ratings in three-phase networks.

The App in German language also includes a second part that deals with a special theme of energy technology, the voltage regulation of transformers with on load tap changers (OLTC). Here, the theme is one of introduction, but detailed explanations are also given, starting with the tasks of such a function, from tap position indication (TPI) through to the parallel operation of transformers.

Furthermore this app includes so-called "Info Letters" published by A. Eberle GmbH & Co. KG over the years to improve the understanding of the technical relationships and special topics of energy technology. The Info Letters will be available in a later update in English as well.

Special thanks go to the co-authors Lothar Mayer, Werner Haussel and Till Sybel, and especially to Helmut Karger who has done the first part of the book alone, and has taken over a large part of the work for the second part.
Sincere thanks also go to Dr. Arentowicz, Johannes Brenner, Andreas Fräbel, Guido Kosanke, Dirk Olschewski and Walter Schossig, who all played a part in the creation of the book.

Outlook:

There is another App called REGSim that enables you to simulate the algorithms discussed here for the parallel operation of transformers and, with the help of appealing visualizations, shows directly how this topic works in practice.
