What Is Definite Time Overcurrent Relay at Claudia Higgins blog

What Is Definite Time Overcurrent Relay. For operation of definite time overcurrent relay operating time is constant The relay does not operate when the fault current is less than preset value and times. Definite time overcurrent relay is used as a backup protection of distance relay of transmission line with time delay, backup. When the current in an overcurrent relay exceeds a critical level, the magnetic effect of the coil activates the moving element, altering the relay’s contact position. Definite mean time over current relay: Definite time of overcurrent relay modern relays may contain more than one stage of protection each stage includes each own current and time setting. The relay operates when the current exceeds the preset value with the fixed operating time which means the relay operating time depending upon the time. I.e if the current must withstand until the operating time exceeds. An overcurrent relay is a protective device that operates solely based on current without the need for a voltage coil. You can use combinations of curve types to achieve the design.
