Description 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
Application 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.

Applications
The Serveron® TM1 offers a breakthrough price/performance point in on-line DGA for distribution and other power transformers in the grid. For the first time, the benefits of on-line condition monitoring can be realized across the distribution transformer fleet. Hydrogen gas buildup in transformer oil is an early indicator of incipient transformer faults. The Serveron® TM1 continuously monitors hydrogen PPM Levels and can be programmed to alarm based on PPM Levels and/or Rate of Change (ROC), warning operators of potentially disruptive transformer faults and pending failures.

Qualitrol Bushing Monitor System is an on-line Tanδ (PF) and Capacitance monitoring system for substation bushings. It measures the phase difference induced by capacitive layers of bushings and calculates the rate of change to predict defects in bushing insulation. It can predict defects related to partial breakdowns, moisture, contact problems and aging of insulation material. Bushing monitoring can be done for LV bushing, HV Bushings and both LV and HV bushing togethers.
· Supports 1 to 6 bushings independently.
· 1 Spare/available module to grow with you and your needs (analog signal, digitals)
· Can integrate 3 party devices and other Qualitrol Transformer monitors (DGA, UHF Partial Discharges Systems, Breather, etc)
