Applications
Qualitrol’s DGA series enables online monitoring of dissolved hydrogen in a variety of transformers including conservator, air and nitrogen blanketed models. Sensors can be easily mounted directly in the insulating oil or in the gas headspace, providing multiple mounting options. Additionally, Qualitrol has integrated hydrogen sensing capabilities in its latest Rapid Pressure Rise Relief (RPRR) design (optional).All this is provided at a market beating low price point to make wide scale deployment even at distribution level affordable.
