Operation of UHV Laboratory: Operation of UHV Laboratory are designed as indoor laboratories or outdoor laboratories depending on the specific requirements. An indoor laboratory is preferred when most of the…
Dielectric Constant and Loss: Many insulating substances have dielectric constant greater than unity and have Dielectric Constant and Loss when subjected to a.c. voltages. These two quantities, namely, the dielectric…
Measurement of High Direct Current: High magnitude direct currents are measured using a resistive shunt of low ohmic value. The voltage drop across the resistance is measured with a millivoltmeter.…
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…
Stepper Motor Applications: The microprocessors are employed for the control of stepper motors which are generally used as position actuators. Some other Stepper Motor Applications are to drive floppy discs,…
Field Oriented Control of Three Phase Induction Motor: The stator current of an induction motor has the functions of producing the required air gap flux (magnetisation) as well as developing…
Function Generation and Linearisation: An important aspect of the closed loop control system is the use of Function Generation and Linearisation, e.g. in the control of induction motors there exists…
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…
