REOVAR DRRT Variable Column Transformers
REOVAR DRRT Variable Column Transformers
For line currents of 34A and higher it becomes more practical to use a column transformer. These comprise a number of tubes wound with copper strip edgeways. Rollers brushes are moved across the face of the windings, through a worm drive. Many tubes can be connected in parallel to carry higher currents and using this technique it has been possible to build variable transformers rated for 3 x 500A.
The output is distortion free and can be adjusted under load conditions.
