Abstract :
The application of differential protection has been shown to be effective in many applications within the Forest Product based industries. However, there are some aspects of differential protection which need special consideration. Some differential configurations may be harmful to the systems to which they were installed to protect. This paper will cover a few of the basics surrounding typical differential applications. Also highlighted are some of the risk areas which are typically overlooked when applying differential protection for certain applications.
