Keyword: «additional losses of electrical energy»

The article presents the results of experimental studies to determine the time of use of the maximum load and the time of greatest losses for the most significant harmonics of the current by seasons. The measurements were performed on low-voltage inputs of 10/0.4 kV power transformers that supply mainly utility networks with a voltage of 0.38 kV. To obtain reliable results, 37 head sections of 0.38 kV networks were examined.
