Centralized power reducing device, particularly for lighting installations
First Claim
1. A centralized power reducing device, particularly for lighting installations, comprising, on each phase of the installation power source:
- a winding (16) in series with a load (10) for varying the voltage to said load (10), said winding wound on a magnetic core (18), said magnetic core having a magnetic field controlled by a current flowing therethrough,a second winding on said magnetic core (18) to control the current flowing through the magnetic core,a multiple-tap autotransformer (22) for controlling the current, said autotransformer being connected by means of relays (24) and being controlled by a logic unit (26).

Abstract
Disclosed herein is a centralized power reducing device, particularly for lighting installations, comprising, on each phase of the installation power source, a winding (16) in series with load (10), wound on a magnetic core (18), the current supplied to load (10) flowing therethrough, a second winding (20) wound on said magnetic core (18), a drive or control current flowing therethrough, means (22, 24) for changing said drive or control current and wherein said means (22,24) for establishing the extent of the drive or control current in said second winding (20) are comprised of a multiple-tap autotransformer (22), the connection of said autotransformer (22) taps occurring by means of relays (24) controlled by a logic unit (26).
