What is anti-islanding protection testing?

Islanding is a technique used in electricity distribution where part of the mains grid will be isolated from normal supply and powered by another source.

There are many dangers that electrical workers face on the job. One of these is called Uncontrolled Islanding, which can create hazardous situations when the power supply resumes and also damage equipment with low quality in an island area safety measures taken by employers to prevent accidents from occurring due to short circuits or other malfunctions caused because there wasn’t enough time spent preparing for them before restoring service after a disruption such as storms etc…

One example of islanding occurs when a grid supply is powered by solar panels. It could be a small, household solar installation or a large, commercial solar plant. Even during a blackout, without controlled prevention, solar panels would continue to feed excess power back into the grid as long as there is an excess at the point of generation.

In some cases, islanding is intentional. When this occurs, an inverter detects a grid event and disconnects from the grid. This creates an island that is intentionally created as a backup power generation system.

How Does Anti-Islanding Work?

Embedded generators, such as diesel and solar power, are connected to the grid and require protection from blackouts. An inverter with anti-islanding protection is also needed to keep these systems working during a blackout.

The inverter is programmed to stop feeding power back to the grid when it senses that the power grid is struggling or has failed.

The importance of anti-islanding protection cannot be overstated. Evoenergy requires all Inverters to be tested every five years in ACT. Stag Electrical is a CEC-accredited solar installer qualified to perform anti-islanding protection testing.

Why is there a requirement to test?

To ensure your inverter is safe, it must be tested at least once every five years. This testing helps to avoid damage to the network, and home appliances and minimises power quality issues.

All owners who have an inverter on their property are required to test it every five years during the application process. Testing is required to comply with Evoenergy Micro Embedded Generation Technical Requirements and Evoenergy LV Embedded Generation Technical Requirements.
