Abstract:
1. An apparatus for measuring imbalance in a paired line comprising: a first contact engagable with a first conductor of said paired line; a second contact engagable with a second conductor of said paired line; measuring means in electrical communication with said first and second contacts for providing a metallic voltage signal generated by an imbalance between said first conductor and said second conductor; a first voltage inlet pathway across which said measuring means electrically communicates with said first contact; a second voltage inlet pathway across which said measuring means electrically communicates with said second contact; a first balanced pathway in electrical communication with said first contact; a second balanced pathway in electrical communication with said second contact, said first balanced pathway substantially electrically balanced with said second balanced pathway; an alternating current source electrically connected to said first contact across said first balanced pathway and to said second contact across said second balanced pathway configured to provide a burst of an alternating current signal at a predetermined frequency to said first and said second conductors of said paired line; a microprocessor configured to initiate said burst of said alternating current signal; a ground pathway connected to said alternating current source; and wherein said measuring means provides said metallic voltage signal in response to said alternating current signal and said microprocessor is further configured to receive data relating to said metallic voltage signal provided by said measuring means.
