short circuit, abnormal connection of low resistance between two points of a circuit that usually causes a high, potentially damaging current to flow.
I think what you really mean to ask is "What does the term "short circuit mean?". The heavy currents due to short circuit cause excessive heating which may result in fire or explosion. This contact causes more electrical energy to be produced within a short time. NO. The low voltage produced by the fault has a very harmful effect on the service given by the power system. What Is A Short Circuit? Hence, a short circuit. A thermal phenomenon corresponding to the energy released into the electrical circuit crossed by the short circuit current I for at time t based on the formula I 2 t and expressed as A 2 s. This thermal effect can cause:

And, as with any short circuit, the immediate impact is a sudden reduction in resistance that causes current to flow in an unimpeded fashion. Types of faults like short circuit conditions in the power system network result in severe economic losses and reduce the reliability of the electrical system. Introduction to Electrical Faults Electrical networks, machines and equipments are often subjected to various types of faults while they are in operation. Hopefully, the circuit breaker will sense the disparity and switch off. Current will only flow IN A CIRCUIT. 4.1 Introduction Like all electrical circuits, busbars need to be protected against the effects of short-circuit currents. When a fault occurs, the characteristic values (such as impedance) of the machines may change from existing values to different values till the fault is cleared. Short Circuit Causes and Effects By Web Master February 25, 2019. Here, too, the circuit is "short," in that it has bypassed the circuit wiring, so a ground fault can technically be defined as one type of short circuit.
A short circuit causes large amounts of power to flow. Short circuits can produce very high temperatures due to the high power dissipation in the circuit.This high temperature can be utilized in the application. The vertical wire drawn next to the vertical capacitor shorts the two terminals of the capacitor. Sometimes short-circuit causes damage to the system.

Open Circuit Fault An open-circuit faults is due to a break in the conductor, as at A (Fig), so that current cannot flow. short circuit of the IGBT occurs across the terminals of the drive, the low inductance of the short circuit results in high di/dt of the short circuit current and the IGBT enters the de-saturation mode quickly. To protect against damage, d • Electrical fires: Short circuit causes flashovers and sparks due to the ionization of air between two conducting paths which further leads to fire as we often observe in news such as building and shopping complex fires. It can cause a lot of heat, sparks, and even fire. Causes of short-circuit: A short circuit in the power system is the result of some kind of abnormal conditions in the system. And, as with any short circuit, the immediate impact is a sudden reduction in resistance that causes current to flow in an unimpeded fashion.
