I work in at a University in a building that is only 16 years old. The reason I mention its age is that it is relatively new as university buildings go. It has appropriate lightning protection, all power lines are in conduit. There is a full TV production and distribution system (approx. $2,000,000 worth) and a remote computer system(control unit, printer, terminals) and a growing number of microcomputers. The line power is relatively[D[C stable, very few flucuation[D[Cs, occasional[D[C power outages during storms. In addition, the building is on an emergency power system, NOT a UPS but a switch to a die[Desiaiesel generator. Up until recently we have not had any transient voltage problems. However, within the last two weeks we have has one AST board go bad and one TV time base corrector power supply. No one can absolutly[Dely[D[C say that these were caused by transients, but they did occur during a period of testing the backup generators and/or scheduled power outage/restart. With all that background the real question is - rather than spend $20 times X for individual surge suppressors scatterd all over the building, what is needed to properly protect the ENTIRE building. The power transformers are located in the basement of the building all in one room. There appear to be two or three secondaries that feed the whole building. -- -Chuck Bennett- UNC - Chapel Hill 919-966-1134 uchuck@ecsvax.UUCP uchuck@unc.BITNET
