Explain Magnetostriction.
Magnetostriction: If ferromagnetic materials are magnetized a small change of dimensions of the material obtains place. There is a small extension along with equivalent reduction of cross-section of the crystals of that the material is made. When this rapidly alternating magnetic fields so there is a rapid and continuous extension and contraction of the material. It is termed as magnetostriction. This magnetostriction is the main cause of hum in transformers and chokes.
Q. A 75-kVA transformer has an iron loss of 1 kW and a full-load copper loss of 1 kW. If the transformer operates on the following load cycle, determine the all-day efficiency:
Find the current flow through each resistor using mesh analysis for the circuit below. Step : Determine the number of common nodes and reference node within the network
Q. For a transmission-line model that includes only the series impedance Z, sketch phasor diagrams for: (a) Lagging power factor load. (b) Leading power factor load.
Q. Name all the switching schemes used in a digital exchange. How call processing occur? Ans: The basic types of switching systems used are: 1. Stronger Switching System
A 100-kW, 230-V shunt generator has R a = 0.05 and R f = 57.5 . If the generator operates at rated voltage, calculate the induced voltage at (a) full load, and (b) one-half fu
Q. Find the currents I x using current division and equivalent resistor reductions for the networks given in Figure.
explain a basic measurement system
Q. A three-phase, three-wire 208-V system is connected to a balanced three-phase load. The line currents ¯ IA, ¯ IB, and ¯ IC are given to be in phase with the line-to-line voltage
The aim of this project is to design, construct and build a motorised base driven by two small dc motors. The motor drives are two H-bridges. The switching devices in these bridges
