| 20080297327 | Coupling of Communications Signals to a Power Line - In one embodiment, a system for coupling a communications signal to a medium-voltage power line includes a surge arrester electrically coupled to a medium-voltage power line and a disconnect device electrically coupled to the surge arrester. The disconnect device is electrically coupled in parallel with a communications device and has a resistance of at least one thousand ohms and a capacitance between one picofarad and twelve picofarads. Furthermore, the disconnect device is electrically coupled to a ground without the use of ferrites. | 12-04-2008 |
