Abstract

A system for measuring a cathode current includes a conducting bar and a current measuring device. The conducting bar has a rectangular plate-like structure, and a first end of the conducting bar is vertically cut to form a plurality of long teeth. The plurality of long teeth are equally spaced at the first end of the conducting bar. The number of the plurality of long teeth is equal to the number of cathodes. The upper surface of each of the long teeth may include a raised conductive contact. Each of the conductive contacts is connected with one cathode of an upstream slot. A second end of the conducting bar is connected with a downstream slot, and the second end of the conducting bar is one end opposite to the first end. The current measuring device is disposed on the conducting bar and used for measuring the current of each cathode.
