Mechanical Information

The Gen5 Hydrogen Sensor is a rugged water proof mechanical assembly design for distribution transformer applications. A ¾”-14 NPT fitting is provided for attachment of the sensor to a transformer.

Measurement Accuracy

There are two types of hydrogen sensors - fuel cell sensors and thin film sensors. Fuel cell sensors consume the hydrogen, and if placed in a small volume of oil, it will eventually degas the oil unless an oil pump or other method of circulation is installed. Thin film sensors do not change the concentration of hydrogen in the oil, and therefore will give a more accurate reading.

Two Installation Options

When fault gases are generated in a transformer, they will be dissolved in the oil where sensors will detect the increasing trend and provide a warning of the equipment problem. Because hydrogen takes time to dissolve in oil, it will accumulate in the headspace quickly. While using an in-oil sensor is effective, the use of a gas space sensor will typically provide a faster response. Both in-oil and gas space sensors are available for use with the B100.
