US Patent:

51948168, Mar 16, 1993

Filed:

Oct 19, 1990

Appl. No.:

7/600464

Inventors:

David S. Steele - Wyoming OH

Assignee:

Westinghouse Electric Corp. - Pittsburgh PA

International Classification:

G01R 3108

US Classification:

324529

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.

Appl. No.:

7/311506

International Classification:

G01N 2742

US Classification:

324425

Abstract:

An instrument for measuring cathodic protection voltage levels receives a signal representative of an externally applied, full-wave rectified power line frequency cathodic protection potential, which is subject to electrical interference. The fundamental power line frequency component and odd harmonics of that fundamental component are removed to produce a filtered signal. Selected parameters of the filtered signal are measured to provide an indication of the adequacy of the cathodic protection potential.
