The topic of master's work:
"Investigation of accidental electric loads influence on a transformer"
The supervisor: prof. Kyrennuy Eduard
I was born in Donetsk on 25 August, 1981. My father is Kravtsov Yuriy Ivanovich, he has been working as a miner since 1981. My mother is Kravtsova Natalia Vasilievna, she's been working as an accountant since 2001. I have also a younger sister Dasha. She's been studying in the first year of Donetsk national university at the Mathematics Department.
I've got a secondary education. I started my schooling at school ¹118 in 1988. Then we moved into another district of Donetsk and I began to study at school ¹40. In 1994 we finally moved into another area and I went to school ¹122. Although I studied at three different schools, only my last one forever remains in my memory. Here I studied for four years and finished it in 1998 with honours. They were the best years of my school life. In this school I met teachers, to whom I'll be grateful all my life for very deep, profound knowledge in all the school subjects and that part of life wisdom, which they shared with me. Firstly it is my History teacher Vorobiev Yuriy Lvovich. Due to him this subject was as vivid as real events, about which he was telling. I'm also very thankful to the English teacher Mogilnikova Ludmila Grigorievna, who taught me to love that beautiful language, and to the Russian teacher Belyaeva Tatyana Nikolaevna, who was my captain in the ocean of Russian. These are teachers with a big letter.
During my school life I was taking part in Physics, Mathematics, Ukrainian, English school Olympiads and I always took prize places. Several times I took part in the region Olympiads in Mathematics and English. As for my school subjects I was fond of Mathematics, Russian, History. But then absolutely by accident I decided to learn English. I've never thought that it would be serious. But now I am "in love" with it and reading English books in the original is my best occupation when I have some spare time. In my school there were a lot of interesting parties in which I took an active part. Especially I remembered a Ukrainian one when I was acting as the main heroine of the play "Nazar Stodolya" after T. G. Shevchenko. It was the part of Galina and I think my debut was rather successful.
I'll always recallect my school years with warmth. In 1998 I entered Donetsk state technical university by rating results. The choice of the higher educational establishment was made because the best specialists teach there who prepare students on a very high level, there are well equiped laboratories and a big library. As for the choice of the department it didn't matter for me then, therefore I couldn't even imagine what my speciality would be. But having studied for four years, I don't regret it.
During my studies at the university I met lots of interesting and wonderful people. I took part in Wiseacres and was awarded the diploma of Donetsk city counsil for the excellent study and active participation in the university life. In the end of the fourth year I passed state exams and got bachelor's diploma with honours. Since the third year I've been engaged into translation of technical texts from Russian into English for my chair (electric supply of industrial enterprises and cities ).
After the fourth year I planned on doing a master's where I started to study processes of transformer heating by an accidental electrical quantity. The final goal of calculations is the determination of transformer service life. The existing methods of the research don't give its accurate solution. That's why I want to investigate this problem under the supervision of the leading specialist of our chair prof. Kyrennuy Eduard Grigorievich. It is an important task because a transformer is one of the most necessary elements in electric supply system and many of industrial processes depend upon its operation. The rise of its elements' temperature can lead to unwanted consequences, shortening of its service life, etc.
This problem was studied by doctor of technical siences Fokin Y. A. and Tretyakov N. V. before me. However, they estimated admissible overloads of a transformer taking into consideration the quantity and duration of overload. That doesn't adequately reflect the heating process of a transformer at accidental change of load.
The results of the research can be used at enterprises for predicting transformer service life, improving its reliability and forecasting its damages. I hope the results of my studies will be required and they will help in the solution of such problems.
In the conclusion I'd like to tell that I face the future with optimism and confidence. After graduating from the university I am planning to find a good job in the firm "Servicinvest". Working at this firm I'll do my best to show myself to be a high level specialist who will yield a profit. I suppose I will be very useful to this organization as a creative person who can work not only in a team but and independently. Meanwhile, I will continue studying English. The result of this work will be receiving of the first Cambridge certificate which will prove a high level of my knowledge in English. It is a very prestigious document because it gives a chance to work in Europe. And I'm going to seize this opportunity. Using received experience, I am planning to work there for five years. At that time I'd like to learn German and French and to travel round Europe. Then, coming back to Donetsk, I will start my own business. It will be connected with technical translations and college of foreign languages. I see that this work is actual and with good prospects because of the development of Ukrainian foreign economics activities and appearance of joint ventures. I wish to round up my story with the words of my favourite prominent Russian writer Anton Pavlovich Chekhov: "In a man everything must be beautiful: and face, and clothes, and soul, and thoughts... ". This is my slogan.
I wish everyone, who visits my site, luck, hapiness and success!
