Line differential protection with PSL 6603U

The PSL 6603U is ideal as an alternative to the Relion® series offering, ultimately suitable as a main 2 solution as it uses a different hardware architecture and its own protection algorithms. Based on a reliable architecture with a redundant CPU and A/D conversion, it applies advanced line differential and distance protection with back-up protection in a configured package, making it very user friendly and intuitive.
