Abstract

A measuring system for electric contact phenomena is described from the viewpoint of simultaneous data acquisition such as arc duration, contact resistance, and material wear, (transfer) under specific operating conditions, in order to find the relationship between contact operating conditions and contact parameters. The system and results from its use are discussed. Contact materials tested are Ag and Pd. The focus is on parallel data acquisition, which is feasible for some, but not all, parameters. Parallel data acquisition resulted in some novel discoveries, which are discussed
