etc. for more info
The protective relaying advanced with the advent of microprocessors to digital (=numerical) relay protection that incorporates many applicable protective functions, often characterized by ANSI Device Numbers (25 for synchrocheck relay) into one integrated numerical protective system that is programmable, flexible, functional, compact, etc.

If communications and event reporting are of any consqence, micorporcessor-based realys are hard to beat.

An application example…

On a systems basis, for synchronization and seeing ‘torsion’ on an interconnected system, GPS clocks make synchrophasors duck soup.

Comment: A compatibility of microprocessor relays with the station power management system is essential. Else, additional hardware interfaces are required, which increase cost and reduce reliability.

Basler Electric has some execellent free materials on-line.

You'll have to register, but for the materials they offer it is well worth while. (The intro to autosynchronization article is great.)
