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.

This course will familiarize participants with the different concepts related to Power Systems Protection. This course is divided into three parts. Part-1 deals with the basics of power systems protection, that include nature of faults, qualities and basic principles of protection, and the components of protection. Part -II deals with the function, operation and classification of Relays. Finally, Part -III deals with the setting of protection relay. By the end of this course participants will be able to: Explain the significance of power system protection Define the nature of faults Explain a few abnormal conditions arising from different types of faults Explain the essential qualities of protection Explain the operation of Protective relay Classify and discuss each type of relay Electromagnetic Relay Static Relay Numerical Relay.

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.
