Education
Linked below are educational resources on overhead and underground transmission line electrical design topics for utility engineers, designers, and operators. Resources cover select EMF related topics for transmission systems including the NESC 5-mA rule for overhead lines and limiting electrical factors for underground cables.
Overhead transmission resource page
Technical information on the electrical characteristics of overhead transmission lines focusing on NESC 5-mA rule compliance for electrostatic contact current (microshocks).
Underground transmission resource page
Technical information on the electrical characteristics of underground transmission cables including cable length constraints and reactive power characteristics.
