The thesis focuses on theoretical and practical calculation of thermal capacity for
certain electrical conductors. With experiments we show the law of conservation of energy, which states that the total energy in the isolated system is constant.
We described the tests for thermal strength of electric wires, that were tested with the device Omicron CPC 100. The device CPC 100 measures the change in current, voltage and resistance over time.
We use CIGRE method to make theoretical calculations. We compare the results obtained from practical experiments with theoretically calculated values and we try to find the difference or the deviation between them.
