Islanding Detection – What, Why and How?
What is Islanding? Islanding is a condition that occurs when a distributed energy resource (DER) such as a grid-tied inverter continues to supply power to a section of the grid that has been disconnected from the main grid. There are two types of islanding: unintentional and intentional. Unintentional islanding occurs when a distributed energy […]

What Is Anti-Islanding Protection?
Passive anti-islanding protection cannot detect an islanding condition on its own but relies on changes in the grid parameters caused by islanding to trigger the protection mechanism. This means that passive protection may not detect certain types of islanding conditions, which could lead to safety hazards and equipment damage.
