Energy Tracking’s WEM-MX Enhanced Next Generation Smart Grid Meter
JUNE 25, 2012

Energy Tracking is announcing the release of its next generation advanced smart grid energy meter. This 4th generation WEM-MX-333mV kWh meter can now directly measure up to 600 VAC without the use of external potential transformers allowing easier lower cost adoption in countries such as Canada for sub metering. This new version is auto ranging from 120 VAC ~ 600 VAC and also works at 50Hz or 60 Hz. This meter complies with the requirements of ANSI C12.1 and also the enhanched accuracy standard ANSI C12.20 Class 0.2 (0.2% accuracy), Watt Hour Accuracy Testing, UL and cUL (Canada). It has a built in web server which can be accessed by MS IE web browser and will support reporting data using XML/SOAP web service client allowing communications via port 80 and eliminating the hassles of going through secure firewalls that too often prevent ftp traffic.

This version uses external current transformers that provide a 333mV secondary output (Safe-CTs). Some of the major advantages of this version is that the current transformers are available in split-core versions that are much lower in cost versus split core current transformers that provide a 5 amp secondary. In addition, the cost of a shorting block is also avoided and current transformers can be installed several hundred feet from the meter.

The WEM-MX combines revenue grade electric metering accuracy and an Ethernet enabled solution for two way communications and reporting. This smart Internet enabled energy meter provides a superior solution with the ability to be accessed in real time via a standard web browser and be configured to send consumption, demand and load profile reports via email, ftp and SOAP every 1 minute if required. More details are provided below.
