Power Quality & RPM User Training - PQ Team Training for electricians, facility maintenance technicians, and facility engineers from non electrical engineering backgrounds. This course is specifically designed for those students who have the day to day responsibility for maintenance or construction of today’s high technology buildings, but who lack the theoretical background of electronic or electrical engineering. It is a 5-day class for facilities staff to increase their competency in identifying, troubleshooting, solving and preventing power quality problems. Today’s high technology building systems requires special skills, experience and the use of complex test equipment. These skills and this knowledge must cross many technical fields. This class is organized around identifying, documenting, solving and preventing those problems associated with the electrical wiring, grounding, data cabling and the quality of the electrical power. The students should have an electrical background, have completed apprenticeship or technical school and be familiar with basic PC operation, MS Windows, MS Word and MS Excel.
