The article addresses two methods of evaluation of control cables for electric utilities that need to be protected from High Altitude Electromagnetic Pulse (HEMP): the first, based on accurate measurements of the cable’s shielding effectiveness using special equipment; and the second, based on information about the cables’ design and marking given in this article. A conclusion is made that the second method does not require significant investments in special equipment and allows evaluation and correct choice of a cable.
