i thought hi-pot test is check for electrical safety of insulation
material under certain voltage. Does it matter if it is class 2 or class
3? please let me know if I am wrong. Did I miss something? is design
margin got something different for different class? if it is, what is the
justification from the design stand to allow such a deviation? for high
voltage, the insulation only as good as the weakest point (thickness
variation for example), what could be the design differantiation that
allowed in class 2 but not class 3? thx in advance.
