Taking into account of its global consumption the eletricity is commodity with high value. That causes the increased interest in its efficient use. There is one possibility how to reach this state and it is strictly necessary (active) power transmission over the power system management. This condition can be achieved by using compensation component carried on a short distance from the appliance. Nowadays the compensation of electricity appears to be technologically well mastered tool that eliminates the negative impacts associated with operation of appliances (inductive or capacitive).
