## Analysis of Unsymmetrical Faults

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…

## Unsymmetrical Faults

Unsymmetrical 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…

## Current Limiting Reactor

Current 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…

## Murray and Varley Loop Test

Murray 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…

## Types of Cable Faults

Types 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,…

## Network Reduction Technique

Network 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…

## Analysis of Symmetrical Faults

Analysis 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…

## Limitation to Fault Current

Limitation 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…

## Formation of Sequence Networks

Formation 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…

## Sequence Impedance and Network of Power System Elements

Sequence 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…
