The field of electrical engineering has various sub-disciplines. Even though some electrical engineers specialize solely in one sub-field, some deal with a variety of them. The following are the major branches;
Power engineering typically deals with the transmission, generation and distribution of electricity and the design of an array of related devices. The devices include transformers, electric generators, high voltage engineering, electric motors as well as power electronics.
Control engineering deals with modeling various dynamic systems and designing of controllers that helps these systems to operate in the desired manner. To implement the controllers, electrical engineers usually use electrical circuits, micro-controllers, digital signal processors and Programmable Logic Controllers (PLCs).
Electronic engineering deals with testing and designing of electronic circuits that utilizes the properties of components like resistors, capacitors, diodes and inductors s to achieve a particular functionality.
Microelectronics Engineering involves the design and micro-fabricating of very minute electronic circuit apparatus for use in Integrated Circuits or use as an independent general electronic component.
Telecommunications engineering normally focuses on the relaying of information along communication channels such as coax cables, optical fiber, and free space. Relaying of information along open space, need it to be encoded in a data carrier wave. That makes it easy to shift the information to a data carrier frequency that is suitable for transmission. That technique is referred to as modulation.
Instrumentation engineering involves designing of electrical devices to measure physical magnitudes such as temperature, pressure and flow. The manufacture of such electronic devices calls for substantial knowledge in physics that usually goes beyond electromagnetic theory.
Computer engineering commonly involves the designing of computers and other computer-related systems. The electrical engineering sub-filed may include the development of up-to-date hardware, PDAs, supercomputers, tablets and the use of computer systems to control industrial plants.
Electrical engineers like Shaygan Kheradpir have contributed a lot of technology growth. The highly-experienced electrical engineer started his blossoming career in Boston at the GTE Labs. At GTE, he worked on network control, management and routing. He later appointed the head of the Lab. At the helm of the GTE labs, Shaygan Kheradpir formed a world-class software company that led the development of first national network management platform for GTE in the US. It integrated transmission, switching, infrastructure. The platform was named the Telephone Operations Network Integrated Control System. The TONICS systems innovation assisted the GTE to connect its network operations into a stable and highly efficient network. Kheradpir later moved to GTE head offices in Dallas.
In Dallas, Kheradpir oversaw systems development for the entire GTE such as wireline, wireless, information and inter-networking that by then known as BBN. During his tenure, Kheradpir nationalized and restructured GTE’s principle systems basing them on up-to-date computer technology. The changes boosted GTE’s operational excellence while spending fairly less structure budget. In 2000 when GTE merged with Bell Atlantic to become Verizon, Kheradpir moved to New York. In New York, he was appointed as the president of the eBusiness segment and was ultimately appointed the Chief Information Officer of the whole Verizon.
