Whitfield's Electrical Craft Principles, 6th edition is the first of a two-volume work that covers the electrical principles syllabi for all major awarding bodies such as BTEC, and City and Guilds. The book is fully illustrated throughout with line diagrams, photographs and drawings. Worked examples are included to aid understanding of the theories and principles presented in its pages. Each chapter concludes with a summary of formulae, a set of written exercises and a multiple-choice test, which makes the book ideal for both classroom and private study.

This book provides a compact yet comprehensive treatment of advanced data-driven signal processing techniques for the analysis and characterization of both ambient power system data and transient oscillations resulting from major disturbances. Inspired by recent developments in multi-sensor data fusion, multi-temporal data assimilation techniques for power system monitoring are proposed and tested in the context of modern wide-area monitoring system architectures. Recent advances in understanding and modeling nonlinear, time-varying power system processes are reviewed and factors affecting the performance these techniques are discussed.

Wide area monitoring, protection and control systems (WAMPACs) have been recognized as the most promising enabling technologies to meet challenges of modern electric power transmission systems, where reliability, economics, environmental and other social objectives must be balanced to optimize the grid assets and satisfy growing electrical demand. To this aim WAMPAC requires precise phasor and frequency information, which are acquired by deploying multiple time synchronized sensors, known as Phasor Measurement Units (PMUs), providing precise synchronized information about voltage and current phasors, frequency and rate-of-change-of-frequency.

Wireless Power Transfer (WPT) serves to transfer power from a grid or storage unit to a device without the need for cable connections. This can be performed by induction, as well as by using radio or microwaves.

Wireless Power Transfer (WPT) enables power to be transferred from a grid or storage unit to a device without the need for cable connections. This can be performed by inductive coupling of magnetic fields as well as by direct radiative transfer via beams of electromagnetic waves, commonly radiowaves, microwaves or lasers. Inductive coupling is the most widely used wireless technology with applications including charging handheld devices, RFID tags, chargers for implantable medical devices, and proposed systems for charging electric vehicles. Applications of radiative power transfer include solar power satellites and wireless powered drone aircraft.

Wood Pole Overhead Lines provides comprehensive coverage of medium voltage wood pole overhead lines. It includes guidance on the planning and mechanical design of overhead lines, as well as details of statutory requirements and the latest UK and European standards affecting UK design of wood pole networks, Sag/tension calculations are explained, and details of the latest work on safe design tension limits to avoid conductor fatigue from vibration are included. The basic characteristics of bare and covered conductors are discussed as well as upgrading possibilities, condition assessment and the latest work on 'health indices' for overhead lines. Other topics include wood pole decay and mitigation methods, maintenance schedules, live line working and basic lightning protection.
