  • Wireless Light Control Helped Reduce Labor and Installation Costs at the Seattle VA Hospital

    Working with energy-efficient lighting service provider, Northwest Edison, The Veteran’s Memorial Hospital in Seattle, Washington completed a renovation of its Facilities building, some office space and several laboratories to provide a more energy-efficient, updated space. The installation was complicated by the fact that the hospital building was constructed in the early 1950s, and budgets were tight.

  • Emerson Offers SolaHD K-Rated Transformers to Address Power Harmonics

    Power harmonics have become an increasingly important issue in today’s industrial environment, a result of the growing number of sensitive electronics, high-powered computers and sophisticated production technology employed on many factory floors, production facilities and labs.

    Harmonics are, essentially, current and voltage with frequencies that are not aligned — also known as non-linear loads.

  • Power Quality

    The quality of power coming into a residence or commercial operation has always been important. You expect a consistent and constant flow of electricity to power whatever you're doing.

    Years ago, homes and businesses could tolerate a certain amount of inconsistency. Other than outright power outages, life and commerce could hum along and never notice any differences in power quality, up to a certain point that is.

  • Why is Power Quality Important?

    Before we begin to discuss why power quality is important, let's answer a few questions about what it is, what it involves and what affects it.

    From the utility or provider standpoint, the main concern is a consistent and uninterrupted voltage supply. Remember that this is not a constant value, but a voltage range. While we might talk about, for instance, a 120-volt AC supply, in reality that is a nominal value for a range.

  • New Generation of Occupancy Sensors Offer Even More Features

    The current trend in occupancy sensors is to pack more features and options in ever smaller packages, making sensor installation quick and efficient, while also promoting the greater use of sensors for both energy savings and security benefits.

    First, sensors are moving towards a lower-profile, cleaner design intended to “flatten” the device against a ceiling or wall.
