Power line coupling device and method
First Claim
1. A power line coupler configured to couple communication signals between a communication device having a first terminal and a second terminal and a power distribution system having a first and a second overhead energized power line conductor, comprising:
- a first lightening arrestor having a first end and a second end;
wherein said first end of said first lightening arrestor is configured to be connected to the first overhead energized power line conductor;
wherein said second end of said first lightening arrestor is configured to be communicatively coupled to the first terminal of the communication device;
a second lightening arrestor having a first end and a second end;
wherein said first end of said second lightening arrestor is configured to be connected to the second overhead energized power line conductor; and
wherein said second end of said second lightening arrestor is configured to be communicatively coupled to the second terminal of the communication device through a coupling to a common ground.
