Cambridge SF6 Breakers leakage and quality

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 sf6 gas leaks into the oil. And the C901S model specifically enables timely maintenance decisions if ever such a leak arises.
