Introduction to Alternator Voltage Regulator Excitation System When the load on the power system changes, alternator voltage regulator the terminal changes. Therefore, to maintain the terminal voltage of the generator excitation of the generator must be decreased voltage within permissible standards, the or increased depending upon the situation prevailing to protect the devices or apparatus

Introduction – Electrical Machine Design Electrical machine design involves application of science and technology to produce cost effective, durable, quality and efficient machines. Also the machines should be designed as per standard specifications. The requirements like low cost and high quality will be conflicting in nature and so a compromise should be made between them.

Automatic Voltage Regulator The function of an electric power system is to convert energy from one of the naturally available forms to electrical form and to transport it to the points of consumption automatic voltage regulator. A properly designed and operated power system should, therefore, meet the following fundamental requirements. Adequate ‘spinning reserve’ must be

Sensors and Transducers Sensors transducers are devices which produce proportional output signal (mechanical, electrical magnetic, ctc.) when exposed to a physical phenomenon (pressure, temperature, displacement, force, etc.). Many devices require sensors for accurate measurement of pressure, position, speed, acceleration or volume. Transducers are devices which converts an input of one form of energy into an

Microprocessor Based Controllers Microprocessors are essential to many of the products we use every day such as TVs, cars, radios, home appliances and of course, computers. Microprocessor based controllers are also called as microcontrollers. Microcontroller is a digital integrated circuit which serves as a heart of many modern control applications. Microprocessors and microcontrollers are similar

Introduction to Real Power Frequency Control Real or Active power frequency control is one of the important control actions to be performed during normal operation of the system to match the system generation with the continuously changing load, in order to maintain the constancy of system frequency to a tolerable limit of ±5%. A change
