Atlikus literatūros apžvalgą, remiantis teoriniais ir eksperimentiniais tyrimais, įsitikinta, kad elektromagnetiniai laukai turi įtakos žmogui ir aplinkai. Elektromagnetinio lauko poveikiui daugiausiai jautri centrinė nervinė ir neuroendokrininė sistemos. Didžiausi elektromagnetinių laukų šaltiniai, gyvenamojoje ir darbo aplinkoje, yra buitiniai prietaisai, elektros perdavimo, transformavimo ir skirstomieji įrenginiai. Elektros įrengimų kuriami elektromagnetiniai laukai, erdvėje sklinda pagal 1/r3; 1/r2 ir 1/r dėsnius. Tai charakteringa tiek elektrinių, tiek magnetinių laukų verčių kitimui. Elektromagnetinių laukų parametrų vertę apsprendžia elektros įrenginių įtampa, srovė ir tiriamo taško padėtis įrenginių atžvilgiu. Įvertinant labai platų mūsų šalies energetikos tinklą, naudojamų elektros įrenginių, kuriančių elektromagnetinius laukus gyvenamoje ir darbo aplinkoje, duomenys apie tai įgauna ženklią socialinę prasmę, sudaroma galimybė prognozuoti galimas silpnų elektromagnetinių laukų poveikio reikšmes, numatyti priemones joms pašalinti. / Literary review, according to theoretical and experimental researches, it was noticed that electromagnetic fields of industrial frequency influence the human and environment. The most sensitive parts to the effect of electromagnetic fields are the nervous system and the neuroendocrine system. The biggest sources of electromagnetic fields are the domestic appliances, the installations of electricity transmission, transference and the distributing installations in residential and working places. Electromagnetic fields are generated with electric installations and spread in space by 1/r3; 1/r2 and 1/r law. It is typical of the value change of electric and magnetic fields. Parameter value of electromagnetic fields is solved with electricity installations tension, stream and the location of analyzed point in point of installations. Summing up the wide energetic net of our country, the fact of usable electric installations (which create electromagnetic fields in residential and working places) assume the marked social signification, there is posed the opportunity to forecast the available values of low electromagnetic fields effect, and to forecast means to remove it.

The aim of this Master’s thesis is the design and reconstruction of the high voltage distribution network for the company E. ON with focus on calculation of the stabilized operation and on the planning of new cable taps from the transformer substation Moravany u Brna. The first part of the theoretical analysis of the work deals with the inclusion of the distribution network into the power system and with principles of development and construction of high voltage networks. The second part includes a general calculation of stabilized operation of the power distribution network and a familiarization with the program PAS Off - Line Bison 4.0. The practical part of the thesis is focused on the calculation of the stabilized operation at the current state of transformer substation Moravany u Brna using the PAS Off - Line Bizon 4.0 V programme. This part also contains the design of six new cable lines which are needed to strengthen the power distribution in the southern part of the city Brno. The closing part of this chapter constitutes of a outdoor and indoor cable line renovation. These cables are connected to the transformer substation Moravany u Brna and a calculation of stabilized operation is also included in this part.
