The anode rod to beam contact for modern aluminum smelting technology is more sensitive to contact condition than it is to applied force [1]. The contact can consume in excess of 12 kW per cell if not prepared and maintained carefully. There can be significant variation in contact resistance across the contacts onany one cell. Validating improvements of only a few mV for the anode rod to beam contact for operating cells can be very challenging.The purpose of this paper is to (i) discuss the variation due to measurement technique, and (ii) establish both theoretical and practical benchmarks for common sized connections. The benchmarks presented here are validated against actual plant datameasured at several smelters.
