Abstract
A system, comprising a bus bar having a first through-hole formed therein and a first current sensor that is disposed adjacent to the first branch. The first through-hole is 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 has different length and/or thickness than the second branch. The first current sensor is arranged to measure an electrical current through the bus bar.
Claims14
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.

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 the second branch of the bus bar, the first branch having different length and/or thickness than the second branch;
- a first current sensor that is disposed adjacent to the first branch, the first current sensor being arranged to measure an electrical current through the bus bar;
- and
- a second current sensor,
- wherein the bus bar includes a first portion and a second portion that is arranged at an angle relative to the first portion, the first through-hole is formed in the first portion, and a second through-hole is formed in the second portion, the second through-hole defining a third branch of the bus bar and a fourth branch of the bus bar, and
- wherein the second current sensor is disposed adjacent to the third branch, the second current sensor having a lower error than the first current sensor with respect to a first range of values of the electrical current, and the second current sensor having a higher error than the first current sensor with respect to a second range of values of the electrical current.
