AUTOMATIC POWER FACTOR CORRECTION SYSTEM

摘要

An automatic power factor correction system (1), for an electrical power installation (3) drawing varying levels of reactive power, measures an electrical parameter of the power drawn by a load (5) of the power installation (3) which is capable of indicating a level of reactive power drawn by the load (5) and couples a combination of capacitors (32) to the power line (4) to compensate for the level of reactive power indicated by the electrical parameter measured. In particular, the system (1) measures the phase angle of the power drawn and calculates a combination of capacitors (32) to connect to the power line (4) to compensate for a measured level of reactive powre.
