Short circuit current calculation. Purpose It plays a very important role to protect & also safety of commercial and industrial electrical equipment like circuit breakers,transformers …etc. What is short circuit current? When two or more conductors are different phases come in contact with each other in a line, transformer or any other power element, then the part of the impedance is shunted out of the circuit due to which a large current flow in the un-faulted phases, such current is called the short circuit current. It reduces the effect of impedance in…
