Qualitrol DGA-LT1 Wireless Dissolved Gas Analyzer and Transformer Monitoring Platform

The Qualitrol DGA-LT1 is a cost effective wireless transformer monitor specifically designed for monitoring failure and safety risks on distribution pad mount transformers.  The DGA-LT1 automatically measures dissolved hydrogen concentration, moisture concentration and temperature of dielectric insulating oil.  The monitor takes only minutes to install and requires no costly power or communications cables.  Data is securely stored and analyzed on the QualConnex platform to provide alert notifications on high concentrations or high rate of increasing concentrations.  The DGA-LT1 brings a cost-effective means to reduce site safety risks and prevent costs associated with unplanned outages due to failures.  The DGA LT1 leverages the QGateway RF to TCP/IP for encrypted and highly secure data transfer.
