Sažetak
Online transformer monitoring systems, including transient monitoring can provide valuable data on power system transient that exist in power network. This presentation deals with possible overvoltages that can exist at power transformer terminals. Real overvoltages from the power network are analyzed and compared with the standard ones. State of the art of transient monitoring and transient data analysis is presented. Presentation outline: - Introduction ; - Online transient monitoring system ; - Lightning and switching overvoltages in the power system ; - EMTP simulation of lightning overvoltages ; - Statistical analysis of recorded overvoltage parameters ; - Conclusions.
