Subject: 50 amps in oil pipeline

Hi Roy,

A gentleman, D.F., recently contacted me about electrical
problems which he attributed to an underground oil pipe
line that crossed his rural property.  He had borrowed
a milligauss meter which had a maximum reading of 10 mG.
This meter pegged at maximum when he was about ten
yards from where he thought the pipe line was buried.

He was asked to approach the pipe line at right angles and
note the spots where the meter read 5 mG and 10 mG.  He was 
then to measure the distance between these two spots.

D. F. later telephoned to indicate that he had measured the 
distance between these two marked spots at 34 feet.

These observations using Biott and Savart's law indicate 
a 60 Hz AC current slightly in excess of 50 amperes
in the pipeline.

Perhaps some of your listees have expertise in oil pipe
lines and might offer suggestions as to:
1. the source/sources of the AC current,
2. methods of remedy and
3. whether or not a DC potential maintained on the 
   pipeline to prevent corrosion is contributing to
   the AC current problem.

Good wishes,
Ed
