Worlds largest salmon feed factory installs ADF

Norwegian company, Skretting AS, is a world leader in the manufacture and supply of aquaculture feeds. Skretting has production facilities in 18 countries, but in this article we will focus on their production site in Averøy, Norway, because it is at this site that two ADF P300s have been installed in order to lower the grid’s overall UTHD (total harmonic voltage distortion).

Each ADF P300 is located on a separate 690V transformer. The purpose of filters is to compensate the harmonics, to lower the THD (total harmonic distortion on the voltage) to below 5%.

The installation and commissioning were performed a couple of weeks ago, and in this application, we used our unique feature, Sensorless control. With Sensorless control, you remove the need for current transformers, and the installation is made even easier.

Both filters are now performing as expected, and Skretting AS can be confident that there will be no additional costs due to voltage harmonics.
