Improved coupling arrangement for power line carrier systems

摘要: A power line carrier system is coupled to two or more phase wires of an electrical transmission by transformers and coaxial lines. Each wire be used provided with a coupling capacitor which respectively one end through impedance matching transformer. The other ends the lines are isolation transformers. Use this arrangement eliminates previously used, exposed unbalanced lines, their inherent disadvantages. Where plurality permits various relative voltage magnitudes phases.
