arrangement for compensation of inductive reactive power

摘要

A power factor correcting means for connection to an AC voltage network includes a transformer with high voltage terminals for connection to the network and low voltage terminals. A capacitor battery is provided for connection to the network, and a controllable inductive element is connected to the low voltage terminal of the transformer. The capacitor battery includes a first part connected to the high voltage terminal of the transformer, and a second part connected to the low voltage terminal of the transformer. The total rated power of the capacitor battery is substantially as great as the maximum reactive power of the inductive element, and the rated power of the second portion of the capacitor battery is between 0.3 and 0.7 times as the maximum reactive power of the inductive element.
