Voltage transient origin localization tests: Short low voltage cable case study

Voltage Transient Propagation Timing (VTPT) can be achieved by the development of a basic tool of Waveform Analysis. This tool is developed on voltage transient reference time estimation under GNSS synchronization. By this tool it can possible to evaluate PQ event causes (e.g., capacitor switching upstream or downstream from monitor position) and/or the correlation of events with ordinary switching operations. For the system protection it is possible to extend TWFL (travelling wave fault locators) technique to distribution systems. Considering the possible improvement on accurate timing based on GNSS, the VTPT analysis has been studied for a Low Voltage (LV) or Medium Voltage (MV) power system behavior evaluation. In this work experimental results are presented relevant to transient propagation analysis on a Low Voltage line with very high spatial resolution.
