All components of an electrical system have some amount of internal resistance, but also resistance relative to other components of the system. When working with a PV system, resistance measurements are typically taken for the following reasons:
- To ensure that a connection made in the system has a low enough resistance to function properly. High resistance connections can create heat and fires.
- To ensure that there is a high resistance between the earth/ground and components of the system that should not have a connection of any kind to the ground like an ungrounded conductor. A low resistance connection in this case would signify a ground fault.
