Abstract
In this paper, the high frequency models of pole-transformers are provided to confirm the feasibility of PLC systems between high and low voltage distribution systems. The impedance of transformers is measured to verify the characteristics of transformers at high frequency from 100[kHz] to 1[MHz] and the equivalent circuits of the transformers were designed based on the measured impedance. The signals transmitted from the primary and the secondary sides of the transformers were measured, respectively. The transmission loss of the transformers was obtained by the measured signals. Numerical analysis using the equivalent circuit is compared to the measured signals. The possibility of communication through pole-transformers is presented by experiments and simulations.
