ABSTRACT:
A method for determining the spacial relationship between concealed elongated conductors wherein a test signal is coupled to a first concealed conductor and conductively coupled to a second adjacent concealed conductor. The relative direction of the current of the test signal on the second conductor is measured on opposite sides of the first conductor. An indication of the relative directions of the current of the test signal on opposite sides of the first conductor can be used to determine if the two conductors are separated or in contact with each other. If the relative direction of the test signal radiated from the second conductor is the same on opposite sides of the first conductor, then the two conductors are separated from each other. If the relative direction of the test signal radiated from the second conductor is opposite on opposite sides of the first conductor, then the two conductors are in contact with each other.
