Summary

The condition of machinery safety is the necessary good knowledge of the basic rules in electrical engineering and its correct application in the electrical equipment of machines. Control system has substantive influence on safe operation of machines and apparatus. It must be designed and realized at the basis of actual degree of risk in accordance with technical standards and directions. After graduating, student will know operating features of individual safety elements and design safety control system with regard for classifying degrees of risk. In this subject, student will meet statutory legislative, basic regulations and directions to providing of safe operation, service and manipulating with electric device, including statutory precaution to put electric products into market, assessment of product agreement and assignment of risk in safe operation of electric devices.

Way of continuous check of knowledge in the course of semester

• Short enter tests before starting of each laboratory measurement to examine of student readiness to make measurement • Reports from each measurement processed on the base of measured values from these measurements and their subsequent processing, completing and assessing. • Continuous verifying of student knowledge in the numerical exercises in a form of debate and inquiries to achieve student active participations in study process. Identify, deduce and search of problem solving and their interpretation by students. • Tests from numerical exercises, eventually from chosen theoretical circuits • Term work and projects on a given theme on the basis of selection, investigation, ordering and final compilation of facts and their processing into final form of given theme.
