Carroll & Meynell 3 Phase Variable Transformers, Enclosed
Carroll & Meynell 3 phase transformers(enclosed) provide a trouble free and efficient way of varying and controlling AC voltages. Variation of the output voltage is achieved by a rotating arm and a carbon brush that rolls around a winding commutator.
These 3 phase variable autotransformers consist of three single phase variacs that are mounted on a common shaft and connected in the “star” vector configuration. The variacs are positioned so that the brush arms on each unit are matched.
This new range of autotransformers uses round carbon brushes, riding out any imperfection which gives a smoother operation. The round Carbon brush should last the lifetime of the unit.
