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.

Instrumentation is the science of automated measurement and control. Applications of this science abound in modern research, industry and everyday living. From automobile engine control systems to home thermostats to aircraft autopilots to the manufacture of pharmaceutical drugs, automation is everywhere around us.

The module focuses on the basic concept of Induction Motors. An Induction Motor is the most modest electrical machine from constructional point of view. Induction motor is basically referred as the horse power of the industry. Induction machine are by far the most common type of motor used in industrial, commercial or residential settings because it has: Simple and rugged construction Low cost and minimum maintenance High dependability and sufficiently high proficiency Needs no additional starting motor and necessity not be synchronized. 

This module will provide a brief overview of Transmission and Distribution of power. 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.

The e-learning course module on Indian Electricity(IE) rules is divided into four parts. By the end of this course the participant will be able to enhance their knowledge in these following areas: Understand the genesis and relevance of IE Rules Basic terms related to IE rules and safety regulations Know about general conditions relating to supply and use of electricity List of safety provisions for electrical installations and apparatus of voltage not exceeding 650 volts Learn Safety requirements for overhead lines, underground cables and generating stations.
