CALISTO is a simple and reliable system for detecting transformer incipient faults at their earliest stage. It provides unequalled stability at low concentration levels and is field-installable in less than 2 hours. The monitor offers additional value through on-line monitoring of dissolved water and can be easily networked for monitoring entire substations. Used in conjunction with other MSS products, such as our Myrkos Portable Fault Gas Analyzer, CALISTO becomes a key element in managing critical transformers.
