TAEV

from Wikipedia, the free encyclopedia

TAEV refers to the technical connection requirements for connection to public supply networks with operating voltages of up to 1000 volts . The national version of the TAEV has been published since 1956 by Oesterreichs Energie , the interest group for the Austrian electrical industry.

history

On August 27, 1956, an agreement was signed between the Federal Guild of Electrical Engineers and Radio Mechanics (today the Federal Guild of Electrical, Alarm Systems and Communication Electronics) and the Association of Austrian Electricity Companies (today: Oesterreichs Energie), on the basis of which the "Technical Connection Conditions with Explanations of the relevant regulations for electrical high-voltage systems with operating voltages up to 1000 V (federal version) ”in agreement with the federal guild of electrical, audio, video and alarm system technicians from Oesterreichs Energie. Under the abbreviation TAEV, this ring binder has been an integral part of the working documents of electrical installers and electrical planners for many years. The aforementioned agreement stipulates that any necessary changes and additions should be published by mutual agreement.

In 1956 Austria was still fully in the phase of reconstruction after the Second World War . The electrotechnical regulations were the beginning of a reorganization. The electrical systems were often in poor condition and the electricity supply companies felt at that time to a certain extent responsible for their control, a task that was assigned to the responsible state governors with the Electrical Engineering Act 1965.

Since then, significant improvements and new regulations have come into force in many areas, especially as a result of the Electrical Engineering Act and the national and international development of electrical engineering regulations, provisions and standards. On the other hand, according to the technical development z. B. the problem of electromagnetic compatibility (EMC) and especially the network perturbations are becoming increasingly important. Compliance with the relevant provisions of the TAEV is z. B. essential for the undisturbed operation of electronic devices on the network.

function

The TAEV have acquired several important functions since their inception:

(1) The TAEV summarizes in particular those technical conditions that are neither regulated in detail by ÖVE / ÖNORM provisions nor by the general conditions for access to the distribution network approved by the state authorities under electricity law (available free of charge from the network operator on request). This mainly includes:

  • Specifications on the technical design of the connection and meter area,
  • Special stipulations by the network operator with the aim of achieving adequate uniformity in the sealable part of the customer system and excluding malfunctions from one customer system to another,
  • Specifications on the permissibility and type of connection of certain devices in terms of EMC, in particular to limit network perturbations. Today more than ever, such specifications are necessary in order to achieve or maintain the quality of public supply required by European standard EN 50160 for all customers. (Further information on this topic can be found in the "Recommendation for the assessment of network perturbations", which was jointly published as a brochure by the Association of Swiss Electricity Companies VSE and Oesterreichs Energie.)

(2) In the Austrian legal system, the electricity system was and is a state matter with regard to the enactment of implementing laws and enforcement. With the Electricity Industry and Organization Act (ElWOG), which is now implementing European liberalization in the field of electricity supply in Austria, there are also some changes in this area. Whereas in the past "General Conditions of Supply ... (AVB)" had to be approved by the respective competent state authority for each electricity company, these TAEVs will in future be replaced by "General Conditions for Network Access" for the current "network operators". The detailed regulations of the AVB in the individual federal states already differ from one another to some extent, and certain differences are to be expected in some details for the new conditions for network access. This is why there has not been and will not be in the past and will not have any national regulations on certain issues. For example, with regard to the demarcation of ownership between network operator and customer as well as for other legal questions, only the “General Conditions for Access to the Distribution Network”, which are now to be approved by the competent authorities on the basis of the ElWOG, are to be used.

With the TAEV, on the other hand, uniform technical specifications were made wherever possible, which are equally advantageous for system installers and system operators. For most of the federal states there are also national or specific specifications of the network operators on technical details as "implementing provisions for the TAEV", or these are currently being revised and are usually available on the respective homepage after completion.

(3) The serious changes to the legal requirements ("Nullungsverordnung" and "Elektrotechnikverordnung 2002") and adjustments to the state of the art, as had to be taken into account in the new installation regulations of the series ÖVE / ÖNORM E 8001, have been incorporated into the TAEV 2008 , although the latest erection regulations that appeared after the ETV was issued were not yet legally binding at the time of going to press. Because most of the stipulations can only be presented in an understandable manner in connection with the relevant ÖVE / ÖNORM provisions, the TAEV have always had the character of a reference work for quick information of the electrical installer. This is evident from the agreement made with the federal guild at the time. The TAEV can neither replace the ÖVE / ÖNORM provisions nor was this ever intended. Also because of the multiple references to the relevant provisions, it is assumed that every system installer has the ÖVE / ÖNORM provisions and ÖNORMS relevant to his work.

(4) With this design, among other things, the suitability of the TAEV as a recognized textbook for vocational schools has emerged over the course of time. With regard to the later practical work of the trainees, this development is to be welcomed and explains the high degree of penetration and the increasing demand. In accordance with the general requirements of the school authorities, the new German spelling was taken into account in the TAEV 2008. We ask for your understanding that technical terms that have been used up to now have been given a new spelling.
