Product Overview
The QualConnex platform consists of 3 main parts. The DGA-LT1, QGateway, and QualConnex web
portal.
DGA-LT1
The DGA-LT1 is a transformer oil sensor array reporting oil hydrogen ppm,
moisture, and temperature. The DGA-LT1 sensor is directly mounted to an
existing valve on the transformer and provides a continuous reading of the
transformer oil. The DGA-LT1 is battery powered and wirelessly transmits
encrypted raw signals via RF (Radio Frequency) to the QGateway without the
need for additional power or communications wires, or cables.
The DGA-LT1 is designed to monitor hydrogen gas, with 100% specificity. Since
hydrogen gas is formed under all known thermal fault conditions in oil filled
transformers it is commonly referred to as the universal fault gas. In addition,
Hydrogen is one of the first gases to be generated, making it an excellent early
indicator of a broad range of fault types.
The monitor is designed and constructed to operate in environmental conditions typical of those found at wind
farms, solar farms, non-hazardous industrial sites, power plants, switchyards, and electrical substations. The
DGA-LT1 is designed to be installed and configured by the user. Due to the battery power, wireless
communication, and simple installation, the DGA-LT1 provides a monitoring solution at a low cost, without the
additional material and labor costs reassociated with the installation of power and communication cables to a
wired monitor / sensor.
