This paper considers online classes for power engineering students. The work embraces two subjects: automation in industry and power engineering and measurements and measuring instruments in power engineering. Both subjects have in common a very important thing from the online teaching and learning point of view. They have laboratory classes, during which students work with real control devices and measuring instruments, that is why it is rather challenging to organize the classes in the online mode. Besides the laboratory classes, the courses under consideration consist of lectures and term project consultations. Having completed the courses students take exams. This paper describes the experience the authors obtained in organizing the classes and teaching techniques that allowed them to provide their students with the necessary skills and knowledge. For the online classes, the authors used several software packages: Cisco Webex, Moodle, CODESYS, and some special programs developed in MPEI university. This paper also describes the results the authors obtained and the difficulties they faced.
