The main task of the thesis is to learn bout the application, design and components of a high voltage reactive power compensation capacitor. In a company where I am learning about working in the development department of high-voltage capacitors, a project has come up where we upgrade the insulation level of an existing product. Overvoltages occur in networks and cause stresses on the insulation, which can compromise the normal operation of the capacitor, so it is important to take care in the choice of insulation and to test it properly.
The work is divided in two parts. The first part presents the theoretical facts that I have already learnt during my time of studying, other were introduced to me during my experience in the company. The theoretical part introduces the capacitor and its function in the system, reactive power compensation, the construction of a high-voltage capacitor and insulation.
Chapter 4 starts the second part, which is practical in nature. It describes how to calculate the dimensions of a high-voltage capacitor. The following are the necessary tests that a capacitor must pass before it can be shipped to the customer. This conclusion summarises the results of the tests, the trends in the use of high voltage capacitors and the new objectives that have emerged from the successful development of a new type of capacitor.
