Claim Text:
1. A power-line-communication (PLC) apparatus for data communication over power lines in a power-line communication system between a PLC collector circuit and its power-line-coupled endpoint circuits that measure power consumption at remotely-located facilities, the apparatus comprising: a data-coupling circuit configured and arranged to communicatively couple data to the power lines for transmission to the PLC collector circuit, the data-coupling circuit including a DC-isolation circuit configured and arranged to isolate circuitry in the data-coupling circuit relative to the power lines; and a feedback circuit connected to the DC-isolation circuit including a power-tap circuit, on an isolated circuitry side of the DC-isolation circuit, the power-tap circuit configured and arranged to provide a feedback signal indicative of an estimate of at least one of power, current and voltage being coupled from the data-coupling circuit through the DC-isolation circuit and to the power lines.
