What is Electrical Engineering/ Technology

Electricity has become the basic need for survival, globally. From household to industrial plants, communication and satellite navigation system, electronic equipment, computers etc., all require electricity. Electrical engineering/ technology thus deal with study and application of electrical systems for use in these different environments.

It equips you with the knowledge of transmission and generation of electrical power, electrical circuit design, electronics, instrumentation, control system, understanding electrical and electronic networks etc. The course also covers the study of electronic devices and circuits involved in measurement, instrumentation, control and protection of electrical equipments and conversion systems.

 

What is Electrical Engineering/ Technology

Concept of computer and recent applications of computer based systems in design, analysis and efficient operation of power system, maintaining quality and security, also included in the course. In Pakistan, generally, it does not include Electronics Engineering. However, “Power Electronics” is considered domain of Electrical Engineering/technology as it deals with application of electronics to power distribution.

The main areas of study in Electrical Engineering are:

Power & Electrical Machine deals with the generation, transmission, and distribution of electricity as well as the design of a range of related devices. These include transformers, electric generators, electric motors, high voltage engineering and power electronics.

Control deals with use electrical circuits, digital signal processors, micro controllers and PLCs (Programmable Logic Controllers) to control various machines for desired behavior. It has wide range of applications from the flight and propulsion systems of commercial airliners to the cruise control present in many modern automobiles. It also plays an important role in industrial automation.

Signal Processing deals with processing of electrical signals (analog or digital). It is a very mathematically oriented and intensive area forming the core of digital signal processing and it is rapidly expanding with new applications in every field of electrical engineering such as communications, control, radar, TV/ Audio/ Video engineering, Power electronics and bio-medical engineering as many already existing analog systems are replaced with their digital counterparts.

Power Electronics deals with controlling power by means of electronics. “Inverters” in our daily life is an example of power electronics application. Instrumentation Instrumentation engineering deals with the design of devices to measure physical quantities such as pressure, flow and temperature. The design of such instrumentation requires a good understanding of physics that often extends beyond electromagnetic theory.
