Fast Flashover Identification Methodology on Brushed DC Machines
Authors: , , ,
Abstract: Direct current machines are applied in several industry sectors, such as steel, paper industry, mining, among others. However, the maintenance of this type of machine is quite complicated. For instance, brush sparking and flashing over can occur after a maintenance period, if interpole windings are connected in the reverse way. Since the commutator and brush assembly are high-wear parts of DC machines, a fast and simple maintenance methodology is necessary to ensure the proper commutation process and augmented equipment performance. This paper presents a research review about DC machines sparking and flashover causes and an experimental analysis with simple, fast and low cost test that can ensure that the interpole connections have been made correctly. This methodology can also be inserted into training protocols and service standards of the maintainers of DC machines.
