the desired tripping time (i.e., time delay for relay coordination and system reliability purposes). The decision to trip open or to close the circuit breaker is made by the relay ... • Electromechanical relays were first introduced in the early 1900s. A typical electromechanical relay is pictured in Figure 4. Electromechanical relays are either

www.philadelphia.edu.joTime-overcurrent relays (ANSI 51 relays) have two basic settings: the pickup current and the time delay settings. The process for determining the time delay setting involves: (1) Calculation of a time delay value in definite-time overcurrent elements (2) Selection in inverse-time overcurrent elements of a time-current curve from a family of curves.
