The purpose of this International Standard is to provide a test procedure to evaluate the
performance of islanding prevention measures used with utility-interconnected PV systems.
This standard describes a guideline for testing the performance of automatic islanding
prevention measures installed in or with single or multi-phase utility interactive PV inverters
connected to the utility grid. The test procedure and criteria described are minimum
requirements that will allow repeatability. Additional requirements or more stringent criteria
may be specified if demonstrable risk can be shown. Inverters and other devices meeting the
requirements of this standard are considered non-islanding as defined in IEC 61727.
This standard may be applied to other types of utility-interconnected systems (e.g. inverter-
based microturbine and fuel cells, induction and synchronous machines). However, technical
review may be necessary for other than inverter-based PV systems.
