Abstract

A method for establishing an Ethernet communication link of a digital protective relay having at least two communication ports (451,S452), includes: configuring physical layers of a first communication port (451) and a second communication port (S452); determining whether or not auto-negotiation with respect to the first communication port (451) or the second communication port (S452) is successful; and replacing configuration information regarding one of physical layers of the first communication port (451) and the second communication port (S452) with configuration information regarding the other of the physical layers of the first communication port (451) and the second communication port (S452) according to whether or not the auto-negotiation with respect to the first communication port (451) and the second communication port (S452) has been successful. Herein the determining of whether or not the auto-negotiation has been successful comprises initiating a timer having a set expiration term and determining whether or not the timer has expired. Although Ethernet ports of the digital protective relay are connected without priority, the digital protective relay may perform the same operation.
