Analysis of Unsymmetrical Faults: 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…
Continue readingUnsymmetrical Faults: The 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…
Continue readingCurrent Limiting Reactor: A 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…
Continue readingMurray and Varley Loop Test: For 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…
Continue readingTypes of Cable Faults: An unsatisfactory feature and performance of cable used in the electrical installation are termed cable faults. There are various types of cable faults such as earth fault,…
Continue readingNetwork Reduction Technique: For 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…
Continue readingAnalysis of Symmetrical Faults: In 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…
Continue readingLimitation to Fault Current: The 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…
Continue readingFormation of Sequence Networks: Here 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…
Continue readingSequence Impedance and Network of Power System Elements: To determine the performance or behavior of a power system under unbalanced conditions it is essential to know sequence impedance and network…
