Abstract
There are a variety of protective relays using different measuring techniques to provide protection for equipment and lines. These include electro-mechanical, solid state, and numerical relay platforms. Within each group, various types of front-end filtering exists. Protection engineers should understand how today´s and yesterday´s relays differ in their approach to protection so they can better provide protection for feeders and other equipment.
