Transformer Losses and Efficiency
Published by Alex Roderick, EE Power – Technical Articles: Transformer Losses and Efficiency, June 16, 2021 In this article we will learn about the four main types of transformer losses and calculations for finding the efficiency of a transformer. Transformers, like all devices, are not perfect. While ideal transformers do not have losses, real transformers haveContinue reading “Transformer Losses and Efficiency”
Effect of Soil Moisture on Current-Carrying Capacity of Low-Voltage Power Cables
Published by Stanislaw CZAPP1, Filip RATKOWSKI1, 2, Gdańsk University of Technology (1), Research & Development Center, Eltel Networks Energetyka SA (2) Abstract. One of the factors affecting current-carrying capacity of underground power cables is the thermal resistivity of soil. Its value in the close proximity of the cable is the most important, and for thisContinue reading “Effect of Soil Moisture on Current-Carrying Capacity of Low-Voltage Power Cables”
