Power Quality for Energy Efficiency Retrofits & Renewable Power
“Keeping Your Electricity Clean as You Go Green” Energy Efficiency Retrofits & Power Quality: Energy efficiency is a popular topic for office buildings as well as both commercial and industrial facilities. Due to the major interest in saving energy, electrical professionals are frequently involved in the design, specification and/or installation of equipment that will reduce energy consumption. Typical energy efficiency projects involve the selection of motors or the use of power electronics equipment or devices which are known to cause electrical disturbances such as harmonics and can also be susceptible to power quality disturbances. This course explains the power quality concerns for two of the most popular retrofits (VFDs and LED lamps). The course explains potential problems, methods to recognize problems after installation and provides recommendations to prevent these problems. Renewable Energy & Power Quality: Many buildings have a combination of power sources including utility, renewable energy inverters, standby generators and uninterruptible power supplies (UPS). This abbreviated seminar compares these power sources from a power quality perspective and offers advice for the proper sizing of these power sources, based upon the intended loads. It demonstrates the various levels of power quality achievable for renewable energy inverters based on various filter […]
