What is PD IEC/TR 60865-2 - short circuit effect calculation standard about?
A short circuit (sometimes abbreviated to short or s/c) is an electrical circuit that allows a current to travel along an unintended path with no or very low electrical impedance. This results in an excessive current flowing through the circuit. A short circuit in the power system is the result of some kind of internal and or external effects.
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
