Abstract
A method and apparatus qualifies a conductor for service and determines imbalance resistance of a conductor. The method and apparatus comprises feeding signals from a controller to termination ends of at least three wires of a conductor. In the controller a resistance difference is determined between first and second wires of the conductor using a measured resistance of one of the three conductor wires as a reference value. The conductor is qualified for services when the resistance difference between the first and second wires is below a threshold.
