The action you have requested is limited to users in the group: Users. Please log in or create an account. Docket ID: (admins only) Thank you for proposing a technical achievement for possible recognition as an IEEE Milestone in Electrical Engineering and Computing. Your efforts help preserve the heritage of technology. Detailed information on the Milestone application process may be found at: Milestone Guidelines and How to Propose a Milestone. At least one of the proposer(s) must be an IEEE Member (including Student Member) in good standing. To the proposer’s knowledge, is this achievement subject to litigation? If the answer is "yes", the proposal cannot proceed further. None Yes No You must be able to answer "yes" to all of the following questions. If the answer to any of the following questions is "no", the proposal cannot proceed further. Contact us at email@example.com if you are unable to answer "yes" to all of the following and would still like to proceed. Is the achievement you are proposing more than 25 years old? Yes No Is the achievement you are proposing within IEEE’s designated fields as defined by IEEE Bylaw I-104.11, namely: Engineering, Computer Sciences and Information Technology, Physical Sciences, Biological and Medical Sciences, Mathematics, Technical Communications, Education, Management, and Law and Policy. Yes No Did the achievement provide a meaningful benefit for humanity? Yes No Was it of at least regional importance? Yes No Has an IEEE Organizational Unit agreed to pay for the milestone plaque(s)? Yes No Has an IEEE Organizational Unit agreed to arrange the dedication ceremony? Yes No Has the IEEE Section in which the milestone is located agreed to take responsibility for the plaque after it is dedicated? Yes No Has the owner of the site given permission to place an IEEE plaque? Yes No Year or range of years in which the achievement occurred: Title of the proposed milestone. (Include date or date range in title. Example: “Alternating Current Electrification, 1886”) Please provide a plaque citation in English summarizing the achievement and its significance. Text absolutely limited by plaque dimensions to 70 words; 60 is preferable for aesthetic reasons. NOTE: The IEEE History Committee shall have final determination on the wording of the citation. Names of living persons are not normally used in citations. Exceptions to this are cases where the person's name is linked to the achievement itself (e.g. the Lempel-Ziv algorithm, Maxwell's Equations, etc.) or where the person's name is so widely recognizeable to the general public that it makes sense to use it. When used, the names should be the names of the engineers, scientists, or technologists who actually made the achievement, rather than managers or executives. For more information and suggestions about writing milestone citations, please visit Helpful Hints on Citations, Plaque Locations. In what IEEE section(s) will the milestone plaque(s) reside? Please specify the IEEE Organizational Unit(s) which have agreed to sponsor the Milestone, and supply name and contact information for the senior officer from those OU(s). Sponsorship has three aspects: 1) Payment for the cost of the plaque(s), 2) Arranging the dedication ceremony, and 3) agreeing to monitor the plaque and to let IEEE History Center staff know in case the plaque needs to be moved, is no longer secure, etc. Number 3 must be done by the IEEE Section(s) in which the plaque(s) is located, but aspects 1 and 2 can be done by any IEEE Organizational Unit, and they need not be the same one. Please note: your email address and contact information will be masked on the website for privacy reasons. Only IEEE History Center Staff will be able to view the email address.

Please include coordinates in decimal format rather than degrees. What is the intended site(s) of the milestone plaque(s) relation to the achievement? The intended site(s) must have a direct connection with the achievement (e.g. where developed, invented, tested, demonstrated, installed, or operated, etc.). A museum where a device or example of the technology is displayed, or the university where the inventor studied, are not, in themselves, sufficient connection for a milestone plaque. Also, please Describe briefly the intended site(s) of the milestone plaque(s). (e.g. Is it corporate buildings? Historic Site? Residential? Are there other historical markers already at the site?) Are the original buildings extant? Please provide the details of the mounting, i.e. on the outside of the building, in the ground floor entrance hall, on a plinth on the grounds, etc. How is the intended plaque site protected/secured, and in what ways is it accessible to the public? If visitors to the plaque site will need to go through security, or make an appointment, please give details as well as the contact information visitors will need in order to arrange to visit the plaque. Who is the present owner of the site(s)? In the space below, please describe in detail: the historic significance of the achievement, its importance to the evolution of electrical and computer engineering and science, its importance to regional/national/international development, its benefits to humanity, the ways the achievement was a significant advance rather than an incremental improvement of existing technology. The material submitted here will constitute the main descriptive article on the ETHW website for readers to learn about the milestone. Space is unlimited, and detail is encouraged. Most milestones require 1000 to 1500 words of support, however there is no word limit. The article should be readable by a wide audience that includes practicing engineers, scholars of history, and the general public. Some examples of the text of good milestone articles are First Radio Astronomical Observations Using Very Long Baseline Interferometry] and G3_Facsimile International Standardization of G3 Facsimile (Do not worry about the formatting of the page, IEEE History Center Staff will do that afterwards.) What is the historical significance of the work (its technological, scientific, or social importance)? It was the first AC electric power system in Croatia and one of first multiphase AC systems in the world. Two generators (42 Hz, 550 kW each) and the transformers were produced by the Hungarian company Ganz. The transmission line from the power plant to the City of Šibenik was 11.5 kilometres long and the municipal distribution grid 3000/110V included six transforming stations. The system Supplied 340 street lights and some electrified houses in the town. Three years later after the first Jaruga power plant, the construction of the second Jaruga hydro plant began. Two three phase, 50 Hz, 5.5 MW generators were installed. A new transmission system was built and local grid enlarged. The historical and social significance of the proposed milestone were presented at the 2007 History of Electro technology Conference in Newark, NJ. What obstacles (technical, political, geographic) needed to be overcome? At the time when Krka - Šibenik was built there was no transmission system for larger distance, Krka-Šibenik was one of first integrated systems. It was a two-phase system in time when major cities like London and Roma had one-phase systems. At the time multiphase systems were considered less secure. With time other cities also adopted multiphase systems, this is kept up until today. What features set this work apart from similar achievements? Ganz & Co had previously built an alternator in Rome Tivoli (A1) - a single-phase generator which remained in operation for a limited time. The Power Plant Jaruga 1 (in the Krka-Šibenik system) held Ganz's first multi-phase generator (A2). Furthermore, the Krka-Šibenik system was unique in many ways. Several Zipernowsky, Bláthy and Déri (who, at the time, all worked for Ganz) inventions were first used in Šibenik: ZBD transformers, Blathy watt-meters, etc. The transmission line was also quite interesting. Built on wooden poles it had 6 wires: 4 power conductors (double two-phase line) and a communication (telephone) line. As the power system was set to operation on the night of 28 August 1895, the telephone line (on the transmission poles) was used for communication between the Supporting texts and citations to establish the dates, location, and importance of the achievement.
