Dear Hr. Sells:
Your letter of March 24, 1980 transmitted questions concerning
'lectrical field gradients s'urrounding the proposed Ilarris-Harnett 500 kV line.
The following information is submitted in response to your questions:
(1)
Haximum Predicted Field Gradients Maximum operating voltage Haximum electrical field within the right-'of-way Maximum electrical field at the edge of the right-of-way 550 IGV 8.4 IGV/M 1.5 IGV/H (2)
Ex ected Electrical Field Gradients Normal operating voltage
,Normal electrical field within right-of-way Normal electrical field at the edge of the right-of-way 525 IGV 6.34 kv/H 1.42 IGV/H

Actual Measurements on Exis tin 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)
