Answer:
here is ur answer
Explanation:
A short circuit in the power system is the result of some kind of abnormal conditions in the system. It may be caused due to internal and or external effects.
1]Internal effects are caused by the breakdown of equipment or transmission lines from the deterioration of insulation in a generator, transformer etc. Such troubles may be due to the aging of insulation. inadequate design or improper installation.
2]External effects causing short circuit include insulation failure due to lightning surges. overloading of equipment causing excessive heating: mechanical damage by public etc.
External effects causing short circuit include insulation failure due to lightning surges. overloading of equipment causing excessive heating: mechanical damage by public etc.Effects of Short-Circuit
The heavy current due to short-circuit causes excessive heating which may result in fire or explosion. Sometimes short-circuit takes the form of an arc and causes considerable damage to the system. For example, an arc on a transmission line not cleared quickly will burn the conductor severely causing it to break, resulting in a long time interruption of the line.The low voltage created by the fault has a very harmful effect on the service rendered by the power system. If the voltage remains low for even a few seconds, the consumer’s motors may be shut down and generators on the power system may become unstable.
