CALISTO ONLINE DGA MODELS
Calisto online DGA monitors for power transformers and other oil-filled electrical assets
Calisto detection monitors:
Calisto Hydrogen + moisture
Calisto is an online DGA detection monitor that provides precise and accurate hydrogen and moisture readings with unequalled stability at low concentration levels. Detect and monitor incipient faults using interference–free hydrogen readings. Correlate moisture behavior with load while monitoring long-term trends.
Calisto 2 Hydrogen, moisture + carbon monoxide
Calisto 2 is an online DGA detection monitor that provides additional measurement of dissolved carbon monoxide, combining early fault detection (hydrogen) and cellulose degradation monitoring. Carbon monoxide is a gas often generated in large quantities when transformer cellulose overheats.
Calisto diagnostic monitors:
Calisto 5 5 fault gases + moisture
Calisto 5 is a multi-gas online DGA diagnostic monitor for the measurement of five Duval Triangle gases through a proprietary chromatographic method.
Calisto 9 Complete DGA + moisture
Calisto 9 is a multi-gas online DGA diagnostic monitor that measures all seven fault gases plus oxygen and nitrogen with industry-leading detection limits.
