It aims to provide advice on the best way forward at the planning stage and on the pitfalls to avoid.

The text explains the historical development of the systems from its beginnings nearly 60 years ago, in order to help readers who may encounter older equipment that has been operating for several years. The history and origin of circuits also enables the reader to see how future developments are likely to occur.

The book is divided into ten chapters starting with an overview of standby and power generating sets which briefly discusses why and where the need for installations arises and describes the systems that are included in a normal standby generating set. Other chapters cover interconnecting the standby and normal supplies, harmonic distortion of the supply, static ups, rotary ups, batteries, kinetic energy as an alternative power source and notes on system installation.

The final chapter gives details on system failures and describes incidents that readers might benefit from.

They demonstrate the need for lateral thinking at the planning or design stage such as lack of ventilation, insufficient protection against driving rain and inadequate supporting structure.
