Calisto T1

All-in-One Condition Monitoring System

Calisto is a simple and reliable system for detecting transformer incipient faults at their earliest stage. It provides unequaled 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 Calisto Condition Monitoring products, such as our Myrkos Portable Fault Gas Analyzer,Calisto becomes a key element in managing critical transformers.

  • The Calisto T1 can build from a single component to a comprehensive transformer monitor covering partial discharge (PD), bushings, operational data and connects to Dissolved Gas Analysis (DGA) and third-party monitors.
  • PD Guard – Doble PD-Guard monitors partial discharge (PD) in the transformer bushings, neutral and inside the main tank; it provides local alarms and will communicate data and notifications across standard interface channels and to networked supervisory systems. Doble PD-Guard analyses PD and EMI signals in the HF, VHF and lower UHF ranges with built-in diagnostic tools.
  • IDD – Doble IDD bushing monitor detects deterioration in bushings, finding abnormalities in the insulation and issuing actionable alerts. It provides leakage current, phase, capacitance, power factor and harmonics analysis for up to six bushings individually. If a voltage reference is available, the Doble IDD will perform both relative and True Power factor to detect issues in bushings and voltage reference devices.
  • iO – Doble iO is a data recorder that accepts current, voltage, temperature and relay inputs and integrates and displays data from multiple sensors and sources, including load or operational data, tap position indicators and inputs from other vendor devices.
