Abstract
A correction system for regulating the power factor of an electrical distribution network in which the phase difference between the potential V and the current I of a distribution line is measured. The voltage V and current I are detected, the phase difference between V and I measured, and the measured phase difference compared with first and second predetermined reference limits. When the measured phase difference is less than a first predetermined reference limit, capacitive loads may be added to the network, and when the phase difference exceeds a second reference limit greater than the first limit, the capacitive loads may be disconnected from the network. The actual demand is monitored and the capacitive loads connected only when the actual demand exceeds a predetermined demand value.
