In the Master Thesis discusses the impact of the bridge connecting the transformer to power system connection to a separate transformers. They were first analyzed the method of calculating the steady operation of the network using the Newton iterative method and the method of calculating short-circuit ratios. It describes the area Slavětice 110kV substation, which is the subject of subsequent calculations. It is also elucidating the function of the bridge connection, advantages and disadvantages. The reason for implementing the bridge operation is to increase the reliability of electricity supply to customers but the major disadvantage is the greater technical and economic performance because increased short circuit current and the need for transmission transformer 400/110kV same type with the same parameters. Point is the practical part, which contains already concrete results taken with the dispatcher software Sinaut. There is a short-circuit resistance compared to short-circuit power substation, then the burden of the elements (transformers, lines) for two specified connection alternatives and four interruptions important elements. Finally, it stated that it can be done with the bridge connection which technical measures. It was discovered that in terms of short-circuit ratios in the present time it is not possible to operate the bridge connection transformers substation Slavětice 110kV and in terms of very different parameters of transformers 400/110kV the operation is not recommended.
