The Gridstream solution offers a two-way network platform that forms the
backbone for grid management solutions ranging from advanced meters to
intelligent switches, reclosers, capacitor banks and RTUs. By incorporating
the Gridstream network communication into GridSense™ monitors such as the
TransformerIQ™ and LineIQ™ solutions, utilities are able to expand their
distribution automation capabilities to full-featured overhead line and
transformer monitoring within a trusted, proven and widely deployed
intelligent communications platform. The GridSense™ LineIQ™ solution provides
intelligent overhead line monitoring, while TransformerIQ™ monitors all
failure modes in transformers from the poletop to the substation.

Utilities across the country are striving to maintain reliable, high-quality
power distribution. Advanced monitoring solutions from Landis+Gyr and
GridSense™ will simplify their task. For instance, American Electric Power
(AEP) recently chose this solution to reliably monitor end-of-line voltage in
their Public Service Company of Oklahoma Project. The GridSense™
TransformerIQ™ equipped with the Landis+Gyr Gridstream radio provides a
cost-effective, easily deployable monitoring solution.
