:: A megger is a good answer if you're interested in the performance of the insulator at relatively high voltages ( ~ 1KV ), but at lower voltages, one would use a nanoammeter, a voltage source, and some careful experiment design including guarding.

That said, I have seen a professionally manufactured device ( ground megger, used to measure low resistances ) which indeed used several D cells in parallel to get more output amperes than one cell could provide, and they were left in parallel when the device was not in use.

Or show me difference beetween the side about Sonel and the side about Megger or Fluke-for me, it's discrimination, that is the EN wikipedia's place for the British and US Companies, and there is no place for Polish company . ( jagokogo ) Preceding contribs ) 07 : 46, 12 November 2012 ( UTC)
