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.

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.

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.
