Technical discussion group for lightning protection, power quality, electrical shock medicine

http://tech.groups.yahoo.com/group/LightningProtection is the Internet's only technical forum for anything to do with power quuality
after electricity leaves the power plant. It requires a (free) Yahoo membership to join; all messages are moderated to eliminate idle chatting and wrong information.
Most general questions have already been answered (use the message search function), and the "links" are valuable.
From the front page:
Welcome! This moderated list is a professional forum for: meteorologists, safety officials, engineers, architects, physicists, laypeople, and medical personnel.
WE DISCUSS: protecting people, electronics and structures from lightning; transient voltage surges; grounding; harmonics; and other power quality concerns. * Medical references to lightning strike recovery are available.
SOME AREAS COVERED ARE: Proper education in lightning safety; Boating safety; Grounding and testing/maintenance; Home protection; Broadcast towers; Fraudulent claims and specifications; * Educating meteorologists, teachers, public safety personnel in accurate lightning facts and safety.
CO-MODERATORS and LIST MEMBERS include recognized experts who generously give their time in fostering accurate information and, especially, saving lives (lightning safety).
THIS LIST IS NOT a substitute for correctly solving site problems. That requires hiring (i.e., paying) a qualified, experienced power quality Electrical Engineer (E.E.) or Professional Engineer (P.E.)! We like hearing about difficult situations and scientifically proven effective solutions.
POSTING MESSAGES: In signing each message, we request that a poster intending to supply authoritative information clearly identify his or her true name and work affiliation (credentials) as well as provide citations for technical advice given. Questions are welcome. ("There are no stupid questions, ....") We moderate all messages to restrict most of the chatter and encourage valid information.
Please examine "Files" and "Links" for useful information. Your questions might already be answered there.
