Capacitance between cable cores will only have an effect if the test was done with AC, in which case the leakage test would be meaningless.
Exactly
where, did I say that a megger test was done with AC?
You know (or should do) that testing long lengths of cable with a megger can cause some serious voltage build-up in the cable under test, this is caused by the cable storing the current from the megger during the test, not unlike a capacitor.
Has no-one else ever seen this at all?
