Introduction to Short Circuit Analysis
PDH Course E204 Page 1 of 40 Introduction to Short Circuit Analysis Course Content A Short Circuit is a low-resistance connection established by accident or intention between two points in an electric Circuit . This excessive electric current potentially causes Circuit damage, overheating, magnetic stress, arcing, fire or explosion. The amount of current that is available in a Short Circuit is determined by the capacity of the system voltage sources and the impedances of the system, including the fault. In Circuit Analysis , the term Short Circuit is used by analogy to designate a zero-impedance connection between two nodes. This forces the two nodes to be at the same voltage. In an ideal Short Circuit , this means there is no resistance and no voltage drop across the Short .
