Electrostatic Generators: Van de Graaff generators are essentially high voltage but low power devices, and their power rating seldom exceeds few tens of kilowatts. As such Electrostatic Generators machine which…
Protection of Alternators: The generating units, especially the larger ones, are relatively few in number and higher in individual cost than most other equipment's. Therefore, it is desirable and necessary…
Sequence Impedance of Power System: Each element of power system will offer impedance to different phase sequence components of current which may not be the same. For example, the impedance…
Requirements of Satisfactory Electric Supply Connection: The Electric Supply Connection in India is 3-phase a.c. operating at a frequency of 50 Hz. The power station delivers power to consumers through…
Power Factor Improvement: The low power factor is mainly due to the fact that most of the power loads are inductive and, therefore, take lagging currents. In order for Power…
Introduction to Microprocessors and Control of Electric Drives: Introduction to Microprocessors and Control of Electric Drives - Conventionally, control of thyristor converter fed electrical drives (both dc and ac) is…
Turbocompressors: The turbocompressors and blowers in the industry require drives rated up to 40 MW. Drives of large rating are also required in steel industry blast furnace blowers in natural…
Paper Mill Process: The raw materials for Paper Mill Process undergo two processes before the paper is available: The pulp is made from the raw materials. This pulp is converted…
