GRIMSBY, England, February 28, 2011 /PRNewswire/ -- Energy Optimizers Limited (EOL) has extended the range of powerful logging features in its plug-in, ZigBee (http://www.zigbee.org/) wireless electricity meters for load analysis in commercial buildings with 230VAC appliances.

The flexibility of wireless communications means that Plogg (http://www.plogginternational.com/) networks can be installed, configured and scaled to suit any business or government structure, from single offices to retail stores to large multi-site organizations. The plug-in format allows for easy installation and connection to mains socket powered appliances. In addition to local site access, the internet connection permits remote access and data retrieval.

Plogg is designed for use in load analysis studies where accuracy and resolution are paramount. The Plogg Manager PC ( http://www.plogginternational.com/ploggproducts.html) interface allows the user to define thirteen different logging parameters for time and electrical performance and to set the logging interval from 1 minute to 1 month. Plogg devices operate with single phase, split 2-phase and balanced 3-phase loads and an external CT version of the Plogg is available for installations with larger, hard-wired, loads of up to 100A.

Plogg instruments offer accuracy and configurability, with self-calibration and interval logging set by the user in customised terminal software as part of the Plogg Manager package. The new download event scheduler is pre-set at 15 minutes and permits data from user assigned Ploggs to be automatically downloaded to the PC.

A powerful Software Development Kit ( http://www.plogginternational.com/ploggproducts.html) provides software engineers with the capability to integrate the Plogg network and data retrieval functions seamlessly into larger third party systems.

"We have worked closely with a number of customers throughout Europe who have provided us with the design and operational feedback required to build a comprehensive load analysis tool." said Shaun Merrick, General Manager, "The measured data can help enormously in understanding the consumption tends of the monitored equipment."
