The capability now exists to easily acquire, measure, visualize and aggregate the electric energy consumption for an entire building or an enterprise right down to the circuit level.  In 2012, Schneider Electric’s Lighting Control division partnered with Activelogix to design and build a product to enhance their Measurement and Verification Panels (MVP) and also be easily retrofitted into existing electric panels (by Schneider Electric and others).  This product is designed to greatly enhance measurement and analysis of electric loads down to the circuit level.

Marketed by Schneider Electric under the trade name “Energy Insight”, this new product provides circuit level details on load, voltage, power factor, current and more and can handle any number of electric panels of different manufacture and multiple configurations, including subpanels.

For retrofits, the product consists of a prefabricated CT strip that can be quickly mounted along each side of a panel bus to measure the individual circuit feeds. The strips are mated to a connector circuit board that handles the aggregation of the individual circuit data streams.  The data management system is designed around a Niagara framework which handles the data flow to the local server.

For new installations, Schneider Electric’s MVP panels can come pre-configured for Energy Insight, allowing fast installation with no additional effort beyond that of a standard panel in most cases.

For visualization, the Energy Insight system boasts a new web based user interface using elements from the Periscope™ Energy Dashboard framework from Activelogix. An entirely new Energy Insight / Periscope MVP “Viewlet” was developed to provide extensive information for each panel, including the panel’s phase data as well as individual circuit data. In addition to capturing all the dynamic activity at a circuit level, dual-level color-coded user configurable load alarms are provided for each circuit, indicating both a momentary load excursion as well as a sustained excessive load alarm.  These alarms are both visible through the viewlet as well as captured in reports for later diagnosis.

An example of the MVP Viewlet with highlighted alarms is shown below:

Zone Analysis

In addition to its extensive visualization and documentation capabilities, Energy Insight also enables “Zone” creation. This powerful feature allows the user to configure individual circuits from one or more panels into “Zones”.  For example, the building engineer can now set up zones for a myriad of virtual loads.   Examples could include:  all lighting in the building, plug loads on 4th floor, HVAC loads by floor, loads by department, etc.  Circuits from one or more panels can belong to multiple zones, enabling the ultimate in configuration and granularity. Zone loads can be trended and visualized, using the inherent Periscope functionality with up to twenty eight separate viewlet formats.  A powerful database historian can document trends and histories deemed important.

contemporary Integration Opportunities

Due to the incorporation of many native Periscope features in the Energy Insight package, existing North America Periscope clients can easily and cost effectively add Energy Insight capability to their Periscope installations, and likewise, Energy Insight installations can cost effectively add the additional capabilities  of Periscope to their energy visualization strategies.

Proven Results

Energy Insight was initially installed in early 2013 at several locations, including the City of Raleigh (NC), where over 20 panels in their metropolitan complex were retrofitted with Energy Insight. This installation was well received and has already led to a number of interesting “Energy Insights” for the city.
