Grid20/20 OptaNODE™ Distribution Transformer Monitor (DTM)

Brand: Itron

The Grid20/20 OptaNODE™ Distribution Transformer Monitor (DTM) represents the next evolutionary step in the smart grid development.

DTMs empower Distribution Optimization and Distribution Automation which further modernizes the grid, facilitates more meaningful ‘big data’ via DTM sensors within the grid, enhances analytics and improves utilities’ ability to leverage greater use of existing assets within the distribution space. 

The Itron RFLAN OpenWay radio/register board communication is integrated with GRID20/20’s patented sensor OptaNODE DTM to offer these benefits.
Features
  • AMI, SCADA, Distributions Automation and Optimization applications
  • Self-contained unit: Metering, Sensing and Communications all integrated within the same device
  • Flexibility to operate in diverse networks: Wired and Wireless communications options available
  • High-accuracy of monitored transformer parameters within all ranges of operation
  • Specially designed to lower deployment costs with lightning-fast plug-and-play installation
