“…It is better to put it in a cable tray or place it under an overhanging deck or in the corner of a beam where it is not directly illuminated by an HIRF. Cables can be protected by a conductive structure (ground plane) if the geometry and layout are chosen carefully [1], [12], resulting in a low transfer impedance between the induced CM current through the structure and an induced voltage in the cable [13].…”

Above deck, cables on naval ships are exposed to highintensity radiated fields and nuclear electromagnetic pulse (NEMP) that may cause conducted interference and generate electromagnetic fields that exceed the immunity levels of commercially available equipment above and below deck. Exposed cables, such as open power plugs or lighting cables, are modeled and characterized both as a monopole antenna perpendicular to the deck and as a transmission line, representing a cable close to the deck. The placement of an illuminated cable close to the deck is a good protection measure for long cables at low frequencies, which includes NEMP protection. The coupled pulse from a high-intensity NEMP illumination is not expected to cause damage on electric installations. It is shown that for exposed cable length of maximum 25 cm and not placed in the line of sight of transmitters above 400 MHz, no additional protection measures are needed.

Above deck cables on naval ships are exposed to High Intensity Radiated Field (HIRF) that may cause conducted interference and generate electromagnetic fields that exceed the immunity levels of commercially available equipment in the protected environment below deck. Exposed cables, such as open power plugs or lighting cables, are modelled and characterised both as a monopole antenna perpendicular to the deck and as a transmission line, representing a cable close to the deck. Below deck, these cables are connected to the power distribution network, which is from an electromagnetic interference point of view, a disordered chaotic set of unmatched transmission lines. It is shown that for exposed cable length of maximum 25 cm and not placed in the line of sight of transmitters above 400 MHz, no additional measures are needed. The effect of a simple filter is analysed.
