(2) Large fault current overheats the system equipment. (3) Some faults block the flow of power. (4) Faults can cause the system to become unstable.
WebWhat Are Surges. In general a surge is a transient wave of current, voltage or power in an electric circuit. In power systems in particular – and this is likely the most common context that we relate surges to – a surge, or transient, is a subcycle overvoltage with a duration of less than a half-cycle of the normal voltage waveform.

In an electric power system, a fault or fault current is any abnormal electric current. For example, a short circuit is a fault in which a live wire touches a neutral or ground wire. An open-circuit fault occurs if a circuit is interrupted by a failure of a current-carrying wire (phase or neutral) or a blown fuse or circuit breaker. … See more A transient fault is a fault that is no longer present if power is disconnected for a short time and then restored; or an insulation fault which only temporarily affects a device's dielectric properties which are restored … See more Asymmetric fault An asymmetric or unbalanced fault does not affect each of the phases equally. Common types of asymmetric fault, and their causes: See more A ground fault (earth fault) is any failure that allows unintended connection of power circuit conductors with the earth. Such faults can … See more Where the system voltage is high enough, an electric arc may form between power system conductors and ground. Such an arc can have a relatively high impedance (compared to the … See more A persistent fault is present regardless of power being applied. Faults in underground power cables are most often persistent due to mechanical damage to the cable, but are sometimes transient in nature due to lightning. See more One extreme is where the fault has zero impedance, giving the maximum prospective short-circuit current. Notionally, all the conductors are considered connected to ground as if by a metallic conductor; this is called a "bolted fault". It would be … See more Realistically, the resistance in a fault can be from close to zero to fairly high relative to the load resistance. A large amount of power may be consumed in the fault, compared with the zero-impedance case where the power is zero. Also, arcs are highly non-linear, … See more WebFeb 24, 2012 · The modern power system deals with huge power network and huge numbers of associated electrical equipment. During a short circuit fault or any other type of electrical fault (such as electric cable faults), a high fault current will flow through this equipment as well as the power network itself. This high current may damage the …
