Qualitrol STB000 Main Tank and LTC Transformer Breather

Qualitrol STB000 Main Tank and LTC Transformer Breather

0.00

The Qualitrol STB series smart transformer breather removes moisture from air entering oil-filled transformers or LTC conservators.

The breather is automated to regenerate the silica gel desiccant at a user selectable time interval, relative humidity (RH) or PPM thresholds. Regenerating the silica gel automatically reduces unnecessary breather maintenance costs over time. Alarms and digital communications allow for remote monitoring of moisture levels and breather status.

Recommended for use on Medium/Large Transformers with a voltage of 1.38kV and above.

Moisture management in transformers

Excess moisture from the atmosphere may degrade a transformer bladder, oil and insulation system over time. This degradation causes unnecessary aging to the asset, reducing the overall life and performance. This can lead to additional maintenance or even premature and unexpected asset failure in the future.

Conventional breathers versus self-dehydrating breathers

Standard transformer breathers require personnel on-site to visually inspect for moisture levels, replace saturated silica gel, and maintain the breather. By comparison, the second generation of Qualitrol dehydrating breathers are self drying and the first universal maintenance free breather available.

These smart breathers can extend the life of your asset.

Features of the STB Series Transformer Breather


LOWER TRANSFORMER MAINTENANCE COSTS

Reduce maintenance costs with learned transformer breathing patterns and self-regenerating desiccant

UNIVERSAL MOISTURE REGULATION

Universal algorithm determines the best regeneration style based on the breathing pattern of the transformer. The STB000 automatically shifts to a time-based regeneration if it is installed on a tank that does not breathe, such as as LTC application, eliminating the need to carry two models in your inventory

BUILT TO LAST

All units have standard C5M coating and carry a 5-year warranty

MONITOR TRANSFORMER MOISTURE LEVELS

Multiple communication options including 4-20 mA, RS-485 MODBUS and local USB port provide allow for trending of moisture readings and regeneration cycles

SIMPLE DIAGNOSTICS

New test button option allows for an easy diagnostic check of breather functions in the field

VISUAL STATUS DISPLAY

External LED indication gives current status of unit including active regeneration

MULTIPLE BREATHER SIZES

Oil desiccant size of 30,000 litres/8,000 gallons

 
 

STB Options


COLD WEATHER

Polar models offer additional internal heaters to withstand harsh temperatures down to -60 °C

OFFSHORE APPLICATIONS

Offshore Xtreme™ models contain material sets specially engineered to adapt to life in harsh marine environments

TRANSFORMER MOUNTING

Multiple mounting options available for new or retrofit installation

MOISTURE PROTECTION

Includes a solenoid valve that closes during the regeneration process to ensure moisture is not wicked into the transformer accidentally

 
Using knowledge gained with our first generation product and gathering customer feedback, we have developed the first universal maintenance free smart breather. It is an exciting innovation for the industry.
