plus and minus leads of the circuit under test are small. The short-circuited option minimizes the chance of exposing array components to voltage levels above those for which they are rated.
1. Scope
1.1 This test method covers a procedure to determine the insulation resistance of a photovoltaic (PV) array (or its component strings), that is, the electrical resistance between the array's internal electrical components and is exposed, electrically conductive, non-current carrying parts and surfac
