MICROTRAN
MicroTran, also known as the UBC version of the EMTP, is probably the most advanced and reliable software tool for the simulation of electromagnetic transients in power systems, and power electronics. MicroTran is used in more than 25 countries and 5 continents for the simulation of switching and lightning surges, transient and temporary overvoltages, electrical machines, resonance phenomena, harmonics, power quality and power electronics applications.
