Compressor is one of the life line of any industry. Many industrial systems depend on compressed air to perform its basic function. The basic objective of this e-learning module on ’compressor’ is to enhance knowledge on working principle of various type of air compressor like screw compressor, centrifugal compressor etc., function and application as well as its classification. In this e-learning module, participant will also learn how to shoot the trouble in a compressor.  

Learning of Power Cable in depth will enable you to define an electrical power cable, explain its construction, describe the guidelines for cable laying and installation, explain the jointing of cables and list the design factors of a power cable. This module will also help you to explain stress control, identify the methods of stress control, describe the method of tracking, explain the method of weathering and define the process of cable maintenance.

Earthing is used to defend us from an electric shock. It does this by providing a protective conductor for a default current to flow to the earth. It also contains a circuit breaker or fuse to switch off the electric current to the circuit that has the fault. This course will help you to define the earthing system, define the significance and purpose of earthing in power systems and define terminologies related to earthing. It will also enable you to identify what needs to be earthed and explain the specifications of the earth continuity conductor.

This module will provide a brief overview of Generation, Transmission and Distribution of power. By the end of this course, the participants will be able to define electrical power generation, illustrate how our home gets electric power, list various sources of energy for power plants, explain construction and working principle of Alternators and Generator Transformers in a power plant and compare various energy sources. The module will also discuss about the transmission line equipment and the various effects observed in Transmission line. It further discusses the electrical power distribution system, list types of distribution system and understand distribution Transformer.

Transformers are electrical devices consisting of two or more coils of wire used to transfer electrical energy by means of changing magnetic field. The transformer does this by linking together two or more electrical circuits by using a common oscillating magnetic circuit which is produced by the transformer itself. A transformer operates on the principles of “Electromagnetic Induction”, in the form of mutual induction. Therefore, the focus of the module is on transformers and its industrial usages.

PLC being the backbone of all the big industry today, the module thus focuses on industrial use of PLC. A Programmable Logic Controller (PLC) or Programmable Controller is an industrial digital computer which has been ruggedized and adapted for the control of manufacturing processes, such as assembly lines or robotic devices, or any activity that requires high reliability control and ease of programming and process fault diagnosis. The main difference from most other computing devices is that PLCs are intended for and therefore tolerant of more severe conditions (such as dust, moisture, heat and cold) while offering extensive input/output (I/O) to connect the PLC to sensors and actuators.
