As you know, the busbar differential protection function (87BB) is the main protection function for protecting busbars, and It relies on Kirchhoff’s current law. This law states that the vectorial sum of all currents flowing into a closed area must be zero.

Topics of busbar protection about how to configure and set the busbar protection parameters are recorded.
