Abstract
Short circuits occur in power systems when equipment insulation fails, due to system overvoltages caused by lightning or switching surges, to insulation contamination, or to other mechanical and natural causes. Careful design, operation, and maintenance can minimize the occurrence of short circuits but cannot eliminate them. Such short-circuit currents (for balanced and unbalanced faults) can be several orders of magnitude larger than normal operating currents and, if allowed to persist, may cause insulation damage, conductor melting, fire, and explosion. Windings and busbars may also suffer mechanical damage due to high magnetic forces during faults. Clearly, faults must be quickly removed from a power system. Hence, proposed journal deals with removal of fault by sensing overcurrent element using Numerical Relay REF615, meant for Feeder Protection. Along with Overcurrent Protection few more protection schemes such as CB Failure Protection and Trip Circuit Supervision (TCS) are also described here. Moreover, Relay Status can also be detected i.e., whether healthy or unhealthy. When we say that system has to be protected against fault, then it means to disconnect faulty part from healthy one by opening CB of corresponding feeder section. In case of CB failure i.e., when Main CB (downstream CB) fails to operate, Backup CB (upstream CB) must be operated after predefined time interval.
