Abstract
The article identifies the difficulties arising from distant training of electro-engineering disciplines, in particular, when conducting laboratory work on the course of physics, electrical engineering and electronics. The advantages and prospects of technical means in education have been analyzed. The achievements of high-quality distance learning based on a computer laboratory of the educational and methodological electrical installation complex have been listed. Functioning of a computer laboratory supposes a connection between the server and the computers of the students and the teacher. One of the ways to implement distance learning using computer technologies when performing laboratory work on electrical disciplines has been presented. There has been considered an algorithm for solving graphical and computational tasks by using experimental data obtained when working with the test bench “Electrical Energy and Electronics”. There have been illustrated the diagrams of an AC rectifier diode, a parametric stabilizer of the electrical circuit voltage on the laboratory bench; the graphs of the current-voltage characteristics of an ideal semiconductor and real diodes, a Schottky diode, a silicon diode at different temperatures, a Zener diode. A diagram of the dependence of semiconductor band gap on temperature is presented. It has been inferred that the students must be IT competent before studying special subjects, in particular, physics and mathematics (specialist’s course “Ship Power plants and Automatic Equipment Operation”; Bachelor’s courses “Shipbuilding”, “Ship Power Plants”), as one of the areas of their professional activities is design and modernization of ships and marine equipment and automation, as well as the analysis of operational characteristics of power plants, which is impossible without special software and technologies. The proposed methods of conducting the laboratory work will prepare the trainees for solving the professional problems.

Summary
Астраханский государственный технический университет, Астрахань, Российская Федерация. Мы предлагаем реализацию дистанционного обучения с использованием скромных технических возможностей вуза, опираясь на компьютерные технологии, которые обеспечивают широкие возможности для постановки лабораторных работ и их проведения. Рассматриваемая нами лабораторная работа «Полупроводниковые диоды» включает: – методические указания к выполнению лабораторной работы с обязательными требованиями по технике безопасности; описание лабораторного модуля, содержащего необходимые данные по теории полупроводниковых диодов; ход выполнения работы предусматривает ознакомление с лабораторной установкой, с работой программы компьютера Delta Profi, порядок действий при выполнении экспериментальных исследований выпрямительного диода, диода Шоттки, стабилитрона, светодиода; – презентацию, которая демонстрирует работу лабораторного модуля, содержащего реальные объекты исследования, на испытательном стенде; – вывод по лабораторной работе (в окончательном виде должен содержать расчетные и графические данные, заполненные таблицы измерений; ответы на контрольные вопросы и задания для самостоятельной работы обучаемого). Сравнить вольт-амперные характеристики (ВАХ) реальных полупроводниковых диодов (рис. 4) и диода Шоттки (рис. 5) на постоянном токе
