Calisto 5

5 Fault Gases + Moisture Diagnostic Monitor

Market-leading DGA sensitivity and accuracy

Avoid what could become a costly transformer failure by choosing our new generation of multi-gas on-line monitors. The Calisto 5 is a powerful tool for transformer condition assessment. This generation of Calistos uses gas chromatography with proven reliable results.This is a physical method of separation in which the components to be separated are distributed between two phases, one of which is stationary (stationary phase) while the other moves in a definite direction (mobile phase).

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.
