Protection Relay

BE1-Flex

The BE1-FLEX Protection, Automation, and Control System is designed to be configurable for nearly any Power System application. The BE1-FLEX can cover a wide application spectrum as it can be configured for any combination of functions available. The large configurable touchscreen provides an application specific user interface. To support unknown future needs, the BE1-FLEX can simply turn on extra functions not common for an application, change or upgrade boards, field upgrade non-hardware style options, and securely update firmware all without needing to remove it from the installation.

BE1-11 series

The BE1-11 digital protection system is designed with many features to address reliability issues that can arise from programming complexity. Correctly setting a protection system has never been easier than with the BE1-11. With BESTspace™ files, multiple BESTlogicTMPlus preprogrammed logic schemes and associated application notes, you can be confident your protection is configured correctly.
