Abstract
This paper reviews applicable standards and references, and describes the reasons for installing various protective elements at the utility-industrial interface. The paper also reviews the operating characteristics of reverse power, load encroachment, and directionally supervised phase overcurrent elements. Real-world event reports will be used to demonstrate problematic applications and common settings mistakes. Lastly, the paper will recommend proper application principles and settings.
