This paper summarizes a project to remotely monitor the performance of four drain bonds which return stray DC current from a Con Edison 345KV pipe-type feeder to the NYC Transit Authority.

It was thought that, since the performance of each of the drains is directly related to the performance of the others, it might be possible to "infer" the performance of three drains by only monitoring the fourth.

The drain at 131st Street was chosen to be monitored because its performance is the most critical to the cathodic protection of this feeder.
