How does the backstopping system work in power distribution?

The backstopping system in power distribution is designed to enhance the reliability and efficiency of the electrical system by managing the loads on the distribution busway. When this system is in operation, it continuously monitors the loading on the busway. If it detects that the load is approaching or exceeding a predetermined threshold, the system can selectively reduce or shed non-critical loads to ensure that the overall system remains stable and avoids overload conditions.

By focusing specifically on busway loading, the backstopping system acts dynamically, allowing it to respond to real-time conditions rather than applying a blanket approach to overload management. This selective shedding helps to maintain service continuity for critical loads while minimizing the risk of outages caused by overloading.
