For the analysis of unsymmetrical faults in the power system network, we require sequence impedance and sequence network concept along with the symmetrical components. The analysis problem will involve positive,…
Continue readingThe types of faults occurring in power systems are symmetrical and unsymmetrical faults. The unsymmetrical fault is the type of fault in which the three-phase line of the system becomes…
Continue readingA current limiting reactor is an inductive coil having a large value of inductive reactance and is put in service for limiting short-circuit currents during a fault condition. We install…
Continue readingFor determining the location of an earth fault or short-circuit fault in an underground cable, we perform a loop test. Murray and Varley loop tests are the two types of…
Continue readingAn unsatisfactory feature and performance of cable used in the electrical installation are termed as cable faults. There are various types of cable faults such as earth fault, short circuit…
Continue readingFor simple power system networks, the analysis of the symmetrical faults can be made easy by the network reduction technique. For modern complex problems, computers are used for these computations….
Continue readingIn power system networks, the symmetrical fault occurs infrequently. A three-phase line-to-line fault is an asymmetrical fault and the occurrence of such fault in the power system network is rare….
Continue readingThe short circuit current produced during a fault in a system is limited by the impedance of the system up to that fault point. So the impedance of the system…
Continue readingHere we will discuss the formation of sequence networks in the power system. Computation of unsymmetrical faults in power systems requires knowledge of sequence networks. Load studies require knowledge of…
Continue readingTo determine the performance or behavior of a power system under unbalanced conditions it is essential to know sequence impedance and network of power system elements. This is a piece…
