3. What is a Transformer?

4. Why Gas Testing? Transformer head space is inerted (made oxygen-free) using nitrogen Internal failures cause electrical arcing between coils which causes the transformer oil to break down and produce flammable gases into the headspace (H2 typical) The Eagle can be used to detect these gases as an early indication of problems

5. Features and Benefits Detects Hydrogen in % LEL / % Vol / ppm Built-in dual pump dilution sampling system Durable long life catalytic bead sensor Sample positive or negative pressure transformers No need for sample bags or external dilution fitting Calibration automatically compensates for dilution of sample Accurately detects flammable gases in inert atmosphere

6. Features and Benefits Audible and visual alarms Powerful pump can draw from transformers with negative internal pressure Able to operate from standard D size alkaline or Ni-Cad batteries 30 hours operation on alkaline batteries 18 hours operation on Ni-Cads

7. Eagle Unique Features The dual pump design is a reliable trouble-free method to provide the necessary dilution of the sample with ambient air This method (as opposed to traditional dilution fitting) is not sensitive to hose length, filter condition, or transformer internal pressures Dilution is automatically compensated for in calibration, no need to multiply or calculate readings
