Because hydrogen is the early indicator of all transformer faults, Morgan Schaffer created the Calisto and Calisto 2 to measure low-level dissolved hydrogen with exceptional accuracy and stability. Both monitors provide additional value with on-line moisture readings. A highly popular model in the Australasian region, the Calisto 2 also monitors dissolved carbon monoxide, a gas often generated when transformer cellulose overheats, providing a more complete picture of the transformer behaviour. Calisto and Calisto 2 are supplied standard with numerous connection options and DNP3.0 and MODBUS communication protocols to allow easy deployment within existing communications and SCADA networks. The Calisto 2 features a unique architecture allowing optional fast swap-over to the multi-gas Calisto 5 or 9 monitor in the event of a significant fault being detected.

Combine early fault detection and monitoring of cellulose degradation
Calisto 2 is Morgan Schaffer’s newest innovation offering compelling value in transformer fault detection and monitoring.
Built to stand the rigours of the Australian climate and to give a maintenance-free 15 year life with no consumables or requirement to replace parts over that time, Calisto 2 offers extremely low whole-of-life cost.
Calisto 2 features unequalled performance and stability for the measurement of moisture and dissolved hydrogen (THE key gas for detecting incipient faults at their earliest stage). It offers unrivalled 2 ppm resolution, 5% accuracy, superb stability of reading, and very fast response to issues (better than 90% of step change detected in just 60 minutes).
Calisto 2 also offers independent measurement of carbon monoxide, a gas often generated in large quantities when transformer cellulose overheats.
Calisto 2 features a very complete communications specification, including optional fibre and IEC61850, and is supplied standard with DNP3.0 and MODBUS communication protocols, thus allowing easy deployment within existing communications and SCADA networks.
It supports all oil types and has been a trusted monitor of choice for the past 15 years in the Australian region with over 17,000 in service in the world today!
Offered with a 30 month warranty, it is very proudly backed for life with exceptional application and field support by AVO New Zealand and Morgan Schaffer.
