Refers to a new Institute of Electrical and Electronics Engineers Recommended Practice entitled 'Monitoring Electric Power Quality' (project number P1159). States the document is designed to define electromagnetic phenomena that can cause power quality problems and recommend methods by which to measure and record these phenomena. Notes increasing concern with power quality problems because of the proliferation of power electronic devices among conventional HVAC equipment. Some equipment can serve as both victim and villain in power quality problems. Summarises the definitions presented in P1159 and describes how the document can contribute to improved operation.
