Abstract

A capacitive unit for local power factor correction of a multi-phase inductive load. The capacitive unit comprises at least one capacitive module. Each capacitive module comprises a contactor and a multi-phase capacitive load arranged to connect to the contactor such that, in use, the multi-phase capacitive load can be connected in parallel with the multi-phase inductive load. The capacitive unit further comprises a central control unit configured to control each of the contactors of the at least one capacitive module so as to control the multi-phase capacitive load applied to the multi- phase inductive load in dependence on the current or the reactive power in at least one phase cable, preferably in all phase cables, providing electric power to the multi-phase inductive load. The central control unit comprises a wireless communication device configured to send operating data of the capacitive unit to an external device.
