Does relay protection include a comparison section
Protection relays detect faults by comparing the quantity (and angles in some cases) of the primary circuit current or voltage to a pre-determined setting. This comparison is done electromechanically for induction-type relays and digitally or electronically for digital or static. The main relay protection functions (overcurrent, directional, differential, distance, etc. ) are briefly explained in this technical article. Effective relay protection depends on accurate calculations, optimal settings, careful coordination, appropriate selection of relays, and thorough. Abstract: Information on the concepts of protection of ac transmission lines is presented in this guide.
