ABSTRACT:
A distribution powerline carrier communication system for providing distribution automation functions. The communication system includes a distribution powerline, with inductive couplers and frequency translating repeaters cooperating to circumvent signal obstructions, such as distribution transformers, and to increase the signal strength. The inductive couplers pick up the communication signals without metallic contact to the primary distribution lines, and the repeaters change the frequency band of the communication signals, enabling the amplifier gain of the repeaters to be selected without limitation due to undesirable feedback and oscillation.
