What is the functional similarity between a thyristor and a BJT? What are their differences? How do you turn the thyristor into the forward conducting status? In the forward conducting status, a thyristor is equivalent to a pair of interconnected BJT. In the following diagram, mark the corresponding BJT types (PNP or NPN) and related terminal types (E.B.C) of each BJT. List two methods of turning off a thyristor from the forward conducting status; after the thyristor is turned off by each method, which state (mode) does the thyristor come into?

Fault Analysis

In an electrical engineering system, a fault is an abnormal electric current flowing through the system, and fault analysis is the study of these faults. For instance, a short-circuit is a fault where the live wire touches the ground or neutral wire. If a circuit is interrupted by a failure of a current-carrying wire then an open circuit fault occurs. The open-circuit faults are also called series faults. One or more phases or ground may be involved in a three-phase fault or may occur only between two phases. Current flows into the earth in case of a ground fault or earth fault. For most situations, the prospective short circuit current of a fault that is predictable can be calculated. To limit the loss of service because of a failure, the protective devices can detect fault conditions and operate circuit breakers and also other devices. All phases equally can be affected in a poly-phase system which is known as symmetric electrical fault. The asymmetric fault becomes more complicated to analyze if only some phases are affected. By using methods such as symmetrical components, the power system analysis of these types of faults is often simplified. The main objective of power system protection is to design, detect, and interrupt power system faults.
