Richard Hughes is looking for information on mains transients...
Several sources of information are:
1) 'IEEE Recommended Practice on Surge Voltages in Low-Voltage AC
Power Circuits' , 1991, IEEE 1. Transients (Electricity) 2. Electric
Circuits - Alternating Current 3. Electric power systems - Protection; ISBN
1-55937-130-7
Abstract: A practical basis is provided for the selection of voltage and
current tests to be applied in evaluating the surge withstand capability of
equipment connected to utility power circuits, primarily in residential,
commercial, and light industrial applications. The recommended practice
covers the origin of surge voltages, rate of occurrence and voltage levels
in unprotected circuits, waveshapes of representative surge voltages,
energy, and source and impedance. three locations categories are defined
according to their relative position from the building service entrance.
For each category, representative waveforms of surge voltages and surge
currents are described, organized in two recommended 'standard waveforms;
and three suggested 'additional waveforms'.
Keywords: acpowr circuits, current tests, surge monitoring, surge test
waveforms, surge voltages, surges, test waveforms, voltage tests, wave
shape.

47th St, NY, NY 100017-2394, USA; ISBN 1-55937-231-1
Abstract: Recommended design, installation, and maintenance practices for
electrical power and grounding (including both power-related and
signal-related noise control) of sensitive electronic processing equipment
used in commercial and industrial applications are presented. The main
objective is to provide a consensus of recommended practices in an area
where conflicting information and confusion, stemming primarily from
different view points of the same problem, having dominated. Practices
herein address electronic equipment performance issues while maintaining a
safe installation A brief description is given of the nature of power
quality problems, possible solutions, and the resources available for
assistance in dealing with problems. Fundamental concepts are reviewed.
Instrumentation and procedures for conducting a survey of the power
distribution system are described. Site surveys and site power analysis
are considered. Case histories are given to illustrate typical problems.
Keywords: commercial applications, electrical power, grounding, industrial
applications sensitive equipment.

8. Specification an Selection of Equipment and Materials
9. Recommended Design and Installation Practices
Additionally, the GE product handbook for their protective devices
has, historically, provided quite a bit of practical information. Other
device manufacturers should be able to provide similar information.
Hope this helps, Richard...
