System-based Testing

Condition Monitoring of Distribution Automation Systems (DAS)

The overall goal of testing protection systems must be to improve system reliability and avoid misoperations of any kind. Nevertheless, we have to accept that the time frame to perform the required testing is limited. If both statements stay true, we must invest our valuable time to perform tests where errors are likely to be made in the protection system. Therefore we will take a general look at misoperation causes in modern protection systems; why today?s testing routines are no longer state of the art; and why this is even more true for complex line protection.  More
