Abstract
Switching operations, faults, lightning surges, and other intended or unintended disturbances cause temporary over voltages and currents in power transmission lines. The system must withstand these over voltages with a certain probability or their effects must be reduced and limited with protective devices. The simulation of transient phenomena is therefore important for coordination of the insulation as well as the proper design of the protection schemes. Such simulation is also needed to analyze unexpected transient phenomena after their occurrence.. By nature these phenomena are combinations of traveling wave effects on overhead lines and cables, and of oscillations of lumped circuits of generators, transformers and other devices. It is practically impossible to study these electromagnetic transients using hand calculations except for very simple cases. This complexity led to the simulation of transients using computer.
