Nowadays, the utility of an electrician must fill out a form for each work using their tablets. However, evaluation of these forms are limited, it is feasible only with manually interpretation of free text fields. The AD&TE Research Group's aim was to develop a new method for processing of the form field. For this, the group used random forest machine learning algorithms to analyze the forms filled in by the mechanics after power errors. The implemented method has over 90% accuracy in determining whether the form is filled after a certain type of fault (temporary short circuit). It has been proved, that in the investigated cases by using machine learning analysis workflows that require free text analysis can be radically simplified, and accelerated.
