Calisto 9

Complete DGA + Moisture Diagnostic Monitor

Market-leading DGA sensitivity and accuracy

The Calisto 9 is a multi-gas dissolved gas analysis monitor that provides the data you need for early detection and diagnosis of impending failures, cost-efficient condition-based maintenance and optimal loading decisions.

Accuracy By Design
Features best-in-market accuracy bench-marked by clients, laboratories, and industry working groups — ensuring the reliability of the DGA results they provide.

Early Detection
Market-leading lower detection limits and a very broad measurement range ensure that you are getting all the information needed to detect and diagnose faults as early as possible.

Easy Deployment
Supplied with DNP3, Modbus and optional IEC 61850 communication protocols for easy deployment within existing communications and SCADA networks.

Fits Your Monitoring Program
Designed to fit your monitoring program, it can operate as a standalone DGA monitor or as part of the Doble Calisto Condition Monitoring Platform.

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.
