QUALITROL STB 100/200 Series Smart transformer breathers
Reduce maintenance costs with learned transformer breathing patterns and self-regenerating desiccant
Обзор
Excess humidity 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.
Возможности
Reduce maintenance costs with learned transformer breathing patterns and self regenerating desiccant:
- Extend asset life by continuously protecting against atmospheric moisture on transformer inhale cycles
- Reduce unnecessary maintenance through self regenerating silica gel desiccant on transformer exhale cycles
- Color changing desiccant gives visual assurance on breather regeneration process
- 4-20 mA signal provides continuous relative humidity (%RH) status
Constructed with robust materials that provide models for almost any application:
- Standard models are designed for most applications and are offered in a variety of sizes (1 kg, 2 kg, 4 kg) all carrying a 5 year warranty
- Polar models offer additional internal heaters to withstand harsh temperatures down to -60 °C
- Offshore Xtreme™ models contain material sets specially engineered to adapt to life in harsh marine environments
- Multiple mounting options available for new or retrofit installation
- Includes a solenoid valve that closes during the regeneration process to ensure moisture is not wicked into the transformer accidentally
User customization through configurable or pre-programmed RH thresholds:
- Desiccant regeneration is configurable by the end user based on % relative humidity (RH) or time frequency (days)
- Color changing silica gel desiccant allows for a visual confirmation of breather regeneration
Local and remote communication options provide for any application:
- Multiple communication options including 4-20 mA, RS-485 MODBUS and local USB port provide for a variety of monitoring solutions for any application
Bright LED indication lights and alarming capabilities indicate breather status:
- Front mounted indication LED lights of green, amber, and red indicate breather status and alarm capabilities
- A guide to the color coded light alarms is displayed on the control box for easy field diagnosis

- STB desiccant size selection
STB breathers are sized to the application based on the quantity of oil housed within the system (main tank + conservator):
Области применения
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 or relative humidity (RH) threshold. Alarming capability and communications reduce unnecessary breather maintenance costs over time. The silica gel may be regenerated many times without replacement due to internal heaters inside the unit that drive off accumulated water on a transformer exhale cycle.
