As a consequence of the increasing competitivity in the current economic environment, Proactive Maintenance practices are gradually becoming more common in industrial environments. In order to implement these practices, large amounts of heterogeneous information must be analysed, such that knowledge about the status of the equipment can be acquired. However, for this data to be of use and before it can be processed by machine learning algorithms, it must go through an exploratory phase. During this step, relationships in the data, redundancy of features and possible meanings can be assessed. In this paper, a number of these procedures are employed, resulting in the discovery of meaningful information. Moreover, a subset of features is selected for future analysis, allowing for the reduction of the feature space from 47 to 32 features.
