Energy management is a growing practice among companies that operate large buildings, campuses, and other complex facilities. Successful energy management requires detailed information on how energy is being used. However, this valuable information is not available in facilities being actively monitored. For effective energy management, facility engineers need to understand exactly how and where energy is being consumed on their properties.

HVAC and refrigeration systems represent between a quarter and a third of total electricity consumption in an average commercial building. Chillers are responsible for over 40% of that demand, making up between 10-12% of a building’s total electricity usage and presenting an opportunity for cost savings. So why are HVAC chillers rarely optimized for efficiency?

What Are You Monitoring?
One critical consideration when searching for a proper power meter is to determine what you're measuring. Is the monitored load signal-phase, split-phase or three-phase? What voltage/current ranges are going to be monitored?
If you're interested in a power meter for residential or light commercial applications, then typically a single or split-phase meter would be the best cho

LEED, the Leadership in Energy and Environmental Design, is the largest driving force behind the increased development of green buildings in the world. One of the most important factors that LEED uses in their certification process is energy consumption and the owner’s ability to track usage and identify potential savings. While most conventional buildings have simple meters provided by the utility company for billing purposes, the advanced standards for LEED certification require more robust and more precise monitoring capability.

Imagine a tone being played by two musical instruments - let’s say middle-C (261.63 Hz). While the pitch played on a piano may be the same as on an electric guitar, its timbre is very different. The sound wave generated from a piano or a simple synthesizer is relatively simple and clean, but the sound wave coming from an electric guitar is often very distorted for effect and contains natural harmonic overtones.

Understanding specific job requirements, such as performance, installation, amperage load and environmental factors is critical to selecting the proper current transformer for an application. Conventional current transformers (CTs) do come with their limitations as they are difficult to install and are lacking in performance and measurement range. Rogowski coils have significant advantages with regards to installation, cost and performance.
