Time overcurrent adaptive relay
International Journal of Electrical Power & Energy Systems, 2003 In this paper we recommend an inverse time overcurrent adaptive relay. This adaptive relay has a greater sensitivity and reduced operating times using only the information available at the relay's site. We herein describe the functional structure of the overcurrent adaptive relay, its implementation and the results obtained in laboratory tests with ...
