Lightning protecting materials used on radar system

Because of the extensive use in modern systems of very sensitive electronic components, lightning strikes does not represent only a threat, but something that cannot be neglected anymore and safety hazards caused by direct and indirect lightning to the aircraft or naval industry. Everyday new materials appear that “can��? protect against lightning. For a new product, the levels of protection against lightning are determined during the design stage. In the case of existing equipments, the situation gets more complicated. The formulation of the military standard MIL-STD- 464A Severe Strike confirms this need. The peak currents of the discharges are between 50 and 200 kA, for the A pulse, 2 kA for the B pulse and 200 to 800 Amps for the C pulse. Experiments have been carried out using a test setup that could duplicate the three discharge components
