Hi All, Apologies if this is off topic.
We are evaluating the merits of Hi-Pot testing on aircraft black boxes as part of the return to service test after a shop repair visit. Most of our black boxes are embedded computer applications that live on the avionics rack in an airplane and perform specific functions like autopilot computer for instance. Some of the box manufacturers specify Hi-Pot testing as part of their return to service tests generally, at around 600 Volts RMS. We have issues with performing potentially destructive tests without restrictions as units that come through the shop for repair. No telling how many times a lemon unit gets zapped. Where we are regulated, we need to have a solid case before we argue with the device manufacturers. What kind of experience do commercial manufacturers have with this sort of testing at manufacture or repair? Is it done commercially? What kinds of things do you find? All feedback on merits / drawbacks is welcome? Thank you.
