Abstract
The paper analyses current and voltage unbalance caused by various unsymmetric loads in MV and HV networks. It refers to a different unbalance definitions and compares them with the values measured by apparatus dedicated to the power quality measurements. If the current unbalance exists, power factors and powers in the electrical lines are not the same as for the symmetrical three-phase loads.
