[DG] [DG] Possible lightening/EMP damage

[Derek - Raymarine - Moderator]

Hi cdiversions

Thank you for your enquiry

Unfortunately a near miss strike can be as disruptive as a direct strike and ESD (Electro Static Discharge) can affect products and cabling in many different ways.

More information regarding the effects of ESD can be found here

It is likely that some parts of your system have failed as a direct result of the ESD, these will need to be replaced, however, it is also possible other parts of the network, cabling, switchgear and product may also have been damaged in some way and so will need to be thoroughly checked and tested and we recommend replaced as a precaution against future failure.

In practice testing will be very difficult since the ESD can damage tracks and ICs inside products and this damage will be very difficult to detect. Once the non-functional items have been replaced, a full visual inspection of all associated cabling should be carried out and is possible fuses and switchgear should also be checked too.

A full functional test of the system will also be required, under load to check for components weakened by ESD but not completely failed.

Regards

Derek
