1. A system, comprising:
a bus bar having a first through-hole formed therein, the first through-hole being arranged to define, at least in part, a first branch of the bus bar and a second branch of the bus bar, the first branch having different length and/or thickness than the second branch; and
a first current sensor that is arranged to measure an electrical current through the bus bar,
wherein the bus bar extends in a first direction and a notch is further formed in the bus bar, the notch, together with the first through-hole, defining a third branch that is formed at an angle relative to the first branch, and
wherein the first current sensor is disposed adjacent to the third branch and arranged to face in a direction in which the first branch is extending.
