Summary
Transient thermal performance of a ground electrode arrangement consisting of concentric cylinders with axis in the earth's surface has been studied. The solutions obtained involve integrals which must be evaluated numerically. Some numerical results are presented, assuming typical moist soil conditions. A procedure is suggested whereby the transient thermal performance of single cylinder arrangements may be predicted.
