Bypass device and method for a power line communications system
First Claim
1. A device for communicating data signals around an attenuating apparatus attached to a power line that attenuates high frequency data signals, comprising:
- a first conductor configured to be electrically connected to the power line on a first side of the attenuating apparatus and a second conductor configured to be connected to a conductor on a second side of the attenuating apparatus;
a first high pass filter;
wherein said first conductor, said second conductor, and said high pass filter are in series with each other and collectively form a first data path; and
wherein said first data path permits the data signals to passively bypass the attenuating apparatus while inhibiting the flow of power around the attenuating apparatus.

Abstract
A passive bypass device for providing a data path around a power meter is provided. The device may be communicatively connected to two low voltage power line energized conductors on a first and a second side of a power meter. The energized power line conductors conduct both the data signals and the power. The bypass device includes a filter that causes the power to pass through the power meter while allowing the data signal to pass around the power meter thereby providing a substantially non-attenuated data signal path. The bypass device may include a first and second data path for the first and second energized conductors and with each path having a high pass filter and a fuse communicatively connected to its respective energized conductor on each side of the power meter.
