ABSTRACT:
Circuits for bi-directionally bypassing a delta-wye transformer with a balanced phase-to-neutral power line communication signal, using passive components. The circuits include a set of three capacitors connected in a wye configuration, each having one side connected to one of the three-phase power lines on the delta side of the transformer. The circuit further includes a network connected from the node of the wye configuration of capacitors to neutral, the network including an inductive reactor with one side connected to neutral and the other connected to the node of the wye windings of the transformer. Component values are selected so that the circuit is resonant from the three phase lines on the delta side of the transformer to neutral. Further, the voltage transformation ratio of the communication signal from the delta side to the wye side is made the same as the corresponding power voltage ratio of the transformer.
