The Calisto™ T1 allows organizations to build from a single component all the way out to a comprehensive transformer monitor. Users can choose to incorporate up to three of the following condition monitoring tools and also link to Dissolved Gas Analysis (DGA) monitors:

  • The best-in-class IDD Bushing Monitor, with relative and true power factor (PF) and harmonic analysis to quickly identify, diagnose and act on deterioration and insulation abnormalities. The embedded alert management system offers three levels of notifications to remove chatter and noise.
  • The iO Multi-Function Data Recorder, a flexible and networkable device that captures, displays and monitors data from any commonly available sensor or module. Dashboards can be accessed via a mobile device or PC independent of cloud connection.
  • The PD-Guard™ Partial Discharge (PD) Monitor, designed to continuously monitor PD in critical and high-risk assets—transformers, rotating machines, cables and switchgear. With built-in detection, advanced diagnostics and data visualization options, the device enables early and quick intervention at the first signs of failure.

"We're committed to going beyond raw numbers to give power and utility companies the context and insights they need to make critical decisions quickly," said Tony McGrail, solutions director at Doble Engineering Company. "The Calisto™ T1 is designed with a highly intuitive, web-based user interface and advanced algorithms that support collaborative, timely investigations and problem solving without having to install proprietary software."

The combined offering – now offered at a lower price – makes Doble's best-in-class condition monitoring solutions accessible to more companies. End users benefit from full functionality of each individual monitor, ensuring peace of mind and reliability in the field. All three modules meet NERC CIP requirements for the utmost cybersecurity protection, and with a built-in web server, no install software is needed to operate the system.
