Improving the efficiency of renewable energy cable networks

The present and future of energy is impossible without the mass use of medium-voltage power cables (6-35 kV). Despite the high quality of modern cables, owners of electrical networks suffer significant economic damage as a result of incorrect selection of type and cross-section of cables, as well as not optimal choice of the mutual arrangement of three phases. Such damage is especially noticeable for long cables, that is, for example, in cases where cables are used to connect wind generators to the electrical network. The article is related to some of these issues.
