US Patent 11862958 Isolation of protection functions in electrical power systems during startup

Systems, devices, and methods include protection functions in an electrical power system. For example, a processing subsystem may include a processor. A memory subsystem may comprise a first memory section and a second memory section. A memory management subsystem may enable memory access only between the processor and only the first memory section to initialize the at least one protection function and, after initialization of the at least one protection function, enable memory access between the processor and the second memory section. Such a configuration may enable the protection functions as fast as possible without waiting for the functions of lesser criticality to be fully loaded and become operational.
