  We are planning a power monitoring system for a new computer facility.  The  
facility will house a combination of mainframe and workstation-class machines,  
all operating from either single-phase 120V or three-phase 120Y/208V buses.   
The monitoring equipment must be configurable (exception levels, activation,  
etc.) remotely via RS-232/422 or ethernet.  The purpose of the monitoring  
system will be primarily to allocate "blame" for computer system anomalies to  
power line glitches, with secondary emphasis on diagnosing power system  
problems.

  So far, we have looked at the Dranetz 626R event monitor.  This is a 5-slot  
mainframe unit, with plug-in modules available for a variety of power  
monitoring needs.  The unit communicates with a local terminal or remote host  
via RS-232, and is controlled by issuing simple ASCII commands.  The 626R will  
probably meet or exceed our needs, but a fully-stuffed unit costs around $10K.

  Does anyone have experience with Dranetz equipment, or with similar equipment  
from other manufacturers?  Please respond by email if possible; I'll post a  
summary if there is significant interest.

Thanks in advance,

Steve
