1. A structural system, comprising:
a structure prone to lightning strikes or icing;
a shielding arrangement electrically connected to a lightning arrangement;
an electric heating arrangement connected to a power source to mitigate icing of the structure;
an electrical insulation arrangement provided between the shielding arrangement and the electric heating arrangement;
the power source housed internally within the structure, the power source electrically connected to the shielding arrangement and to the heating arrangement to apply a predetermined amount of electric test or maintenance energy between the shielding arrangement and the electric heating arrangement; and
a determination device electrically connected to the shielding arrangement and to the electric heating arrangement and configured to determine a shield-heating-voltage or a shield-heating-current present between the shielding arrangement and the electric heating arrangement, wherein the shield-heating-voltage or the shield-heating-current are caused by provision of the predetermined electric test or maintenance energy.
