[EN] Currently in three-phase distribution networks, especially low-voltage networks, there are some inefficient powers. These are defined as reactive power, unbalanced power owing to linear loads, power owing to supply ...
[EN] Low-voltage distribution systems are typically unbalanced. These ine¿ciencies cause unbalanced powers that can significantly increase the apparent power of the system. Analysing and measuring these ine¿cient powers ...

[EN] Recent low-voltage, three-phase distribution networks carry inefficient power, which can
be attributed to the reactive power, imbalance of linear loads, and increase in non-linear
loads. Researchers have mainly focused ...
