Morgan Schaffer Calisto 1

A simple and reliable solution for monitoring transformer fleets cost effectively. The monitor measures dissolved hydrogen with unequalled stability at low concentrations, making it ideal for detecting incipient transformer faults at their earliest stage. Calisto offers additional value through on-line monitoring of moisture in oil. Used in conjunction with Morgan Schaffer portable analysers or laboratory analysis services, Calisto provides outstanding value for protecting your transformer assets.

Morgan Schaffer Calisto 2

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.
