Power Audit-2008

Prior to the summer shutdown, VATT manager Duffek coordinated a power audit for the observatory site. This audit was ordered to determine phase balancing of the observatory’s electrical power distribution system and proper grounding of the VATT building ground grid to the microwave communications tower. The report generated from the power audit showed that the building phases were well within 10% of balance. A few electrical code violations were identified as well as excessive UPS ground currents. Franz and Gray took on the task of fixing the code violations, and they rectified all UPS ground problems by isolating building ground from UPS ground.
