How to Detect sf6 o2 tanks for transformers

It is the responsibility of the transformer owner to regulate these three components over the life of the transformer in order to get as much life out of the transformer as possible. The temperature can be controlled by maintaining the cooling system and regulating the load. Oxygen can be controlled by maintaining the oil preservation system.

  • Is SF6 Dissolved in Your Transformer Oil? - Doble Engineering

    The C901S monitor can detect the first appearance of an SF 6 leak into the oil and quantify changes in leak severity over time. Calisto DGA monitors are ideal for assessing the health of transformers in GIS facilities. They provide accurate DGA data no matter if SF 6 leaks into the oil. And the C901S model specifically enables timely maintenance decisions if ever such a leak arises.
