Pure Liquids and Commercial Liquids: Pure liquids are those which are chemically pure and do not contain any other impurity even in traces of 1 in I09, and are structurally…
Vacuum Breakdown: In the Townsend type of discharge in a gas described earlier, electrons get multiplied due to various ionization processes and an electron avalanche is formed. In a high…
Breakdown in Non Uniform Fields: In Breakdown in Non Uniform Fields, such as coaxial cylinders, point-plane and sphere-plane gaps, the applied field varies across the gap. Similarly, Townsend's first ionization…
Capacitance of 3 Core Cables: The Capacitance of 3 Core Cables is much more important than that of overhead line because in cables (i) conductors are nearer to each other…
Microprocessor Control of a Current source Inverter Fed Synchronous Motor: A drive system employing a Current source Inverter Fed Synchronous Motor has the following features: A four quadrant drive can…
Speed Detector: One important factor in the closed loop control of variable speed drives emÂploying solid state converters is the Speed Detector. In the dedicated hardware control using analog components,…
Hardware Systems Versus Microprocessor Control: The Hardware Systems Versus Microprocessor Control control of electric drives offers the following advantages when compared to the dedicated hardware control. As has already been…
Block Diagram of Electric Drive System: It is normal practice in control engineering to represent a control system by means of a Block Diagram of Electric Drive System, with a…
