Protection Coordination
An electrical engineering concept in which the trip currents and times of circuit breakers, fuses or electronic protection devices at each level are set so that only the device closest to a fault operates when a fault occurs, avoiding cascading trips that cause widespread outages. In programmable power systems it is partly implemented in software, and its difficulty increases as operating modes change.
Timeline (last 90 days)
Protection coordination is an established concept in electrical engineering, referring to setting the trip currents and times of circuit breakers, fuses, or electronic protection at each level to ensure that when a fault occurs, only the protection device closest to the fault point operates, avoiding cascading trips that cause widespread outages.
In programmable power systems such as SSTs, protection logic is partly implemented in software, and the system may switch among AC, DC, and energy storage modes, changing the fault current path accordingly, which significantly increases the difficulty of protection coordination.
