“Electromagnetic transients (EMTs) of any kinds are present on power systems, originated from several sources, such like faults on transmission lines. Transients simulations in power systems are thus required, and many tools are currently available aiming at this issue, as EMT-type programs, alongside with approaches of numerical electromagnetic analysis (NEA). Among different NEA methods, the Transmission Line Modelling (TLM) method has been applied to the solution of many electromagnetic problems, and even to electronic circuit simulation, for its versatility and stability. Most of the numerical transient simulations on power systems are related to faults, whether for protection, reliability or power quality assessments. Regarding the reliability, a common problem faced by the utilities is the fault location, whose results from the existing methods might be inaccurate or demanding expensive equipment in some specific cases. One of the new methods that have been published for the fault location problem is the Electromagnetic Time Reversal (EMTR), which works exactly on the fault-generated transients to evaluate the fault location. Therefore, the present work proposes the utilisation of the TLM as the NEA method for power system modelling and simulation, applying it to the case of fault location on power systems based on the EMTR method. Still, contributions on both the TLM models of power system components and the use of the EMTR-based fault-location technique are therefore pursued.
