Abstract

405,773. Supply systems. BRITISH THOMSON - HOUSTON CO., Ltd., Crown House, Aldwych, London, and COE, R. T., Brandreth, Dunchurch Road, Overslade, Rugby. Nov. 23, 1932, No. 33148. [Class 38 (iv).] Depending on two or more machines running generators in series ;controlling power factor by auxiliary machines.- An arrangement for eliminating undesirable harmonics in an electric circuit S1 comprises generators H1, H2 of harmonic voltages and a condenser C connected in series across the circuit S1. The generators are driven preferably by means of synchronous motors M1, M2 and the phase of the injected harmonics can be varied by rocking the stators. The condenser gives a back e.m.f. in the circuit of fundamental frequency and thus avoids the necessity of using an additional series connected generator of fundamental frequency. Each harmonic generator is provided with a low resistance squirrel cage winding in the pole face to effect balance of the armature reaction. A switch T is provided to enable the generators to be switched out and the condenser to be used for power-factor correction. A polyphase arrangement is described. When used with a high voltage circuit the apparatus can be coupled through a transformer.
