Passive AC Circuits: An Introduction to AC Power and Applications By J.R. Lambert
Paperback: $66.00
Prints in 3-5 business days
AC Circuits and Power Applications is an introductory engineering technology text covering single and three-phase alternating current (AC) power sources, components, connections and loads. Topical... More > coverage includes introductory sinusoidal voltage and phase angle considerations; vector representation of alternating voltages; resistance, reactance, impedance and phase angle determination; single and polyphase transformer operation; polyphase power distribution; common residential and industrial load determination; Wye and Delta transformer connections; power transfer, power factor and power factor correction; balanced and unbalanced resistive and reactive load computations. Diodes, rectifier circuits, AC induction motors and variable frequency drive (VFD) control of induction motors are also investigated. An understanding of direct current (DC) electrical/electronic circuit theory and right-angle trigonometry is strongly suggested.< Less
Application of Reactive Energy and Embedded Generation Effects On Low Voltage Networks Performance By Remon Atfy
eBook (PDF): $25.00
The deployment of reactive compensation and DG brings ample technological and environmental benefits to the traditional distribution networks. The appropriate sizing and placement of capacitors banks... More > and DG help to reduce power losses and avoid transmission and distribution system expansion. The simulator used is OpenDSS and it is primarily designed to simulate the low-voltage systems, with the unique ability to analyse the unbalanced three phase systems , especially with the connection of distributed generation. A study into the effect of reactive compensation applied to LV networks has shown that shunt compensation applied at the main substation may be useful to limit the voltage drop across the transformer. However, downstream compensation is not so effective in reducing feeder voltage drop but may help to reduce network currents and help to operate within cable ampacity. Moderate quantities of embedded generation can alleviate voltage drops and current loading along feeders.< Less
