Your letter of March 24, 1980 transmitted questions concerning electrical field gradients surrounding the proposed Harris-Harnett 500 kV line.
The following information is submitted in response to your questions:
(1)
Maximum Predicted'Pield Gradierits Maximum operating voltage Maximum electrical field within the right-of-way Maximum electrical field at the edge of the right-of-way 550 kv 8.4 kv/M 1.5 kv/M (2)
Ex ected Electrical Field Gradients Normal operati.ng voltage Normal electrical field within right-of-way Normal electrical field at the edge of the right-of-way 525 kv 6.34 kv/M 1.42 kV/M 411 Fayetteville Street o P. O. Box 1551 o Raleigh, N. C. 27602 8064 2sv'foal

Actual Measurements on Existin 500 kV Lines The proposed 500 kV structure for the Harris-Harnett Line is a triangular configuration with three 1590 MCM 45/7 ACSR conductors per phase.
The sub-conductors are 18 inches apart.
The center phase is 29.8 feet above the two outside phases.
The outside phases are 42.4 feet apart.
This design is not yet in service; therefore, actual field measurements are not available.
Please advise us if you have any further questions concerning the proposed Harris-Harnett 500 kV line.
Yours very truly, SDF/jc (1156)
