Electricity do you need to measure it?

Energy measurement and control. Ray Porter. Energy Economics (01604 722333). 90 pages hardback. ISBN 09530534 07. Price £25

This fairly simple book covers the practical aspects of measuring electrical energy consumption on an industrial plant.

After a review of electricity meters, the book then covers current transformers, and transducers. Typical instruments from Crompton Instruments and MTE are illustrated with different types of meter and indication.

Text then continues with details of different forms of data collection available, with examples shown of systems from Northern Design Electronics and Polymeters Response, including details of portable recorders.

Methods for power factor correction and the cause and curing of harmonics round up this practical publication.
