Adiradh offers the Doble Calisto 2 Hydrogen, Moisture + Carbon Monoxide Detection Monitor for online monitoring of power transformers and oil-filled electrical equipment. It measures three important values in transformer insulating oil: dissolved hydrogen, moisture and carbon monoxide. Therefore, it helps users check transformer health and detect early signs of possible faults. Hydrogen can indicate developing electrical faults inside transformers. Similarly, carbon monoxide can provide information about the ageing of paper insulation. In addition, moisture levels help users check the condition of transformer insulation. Moreover, continuous online monitoring allows maintenance teams to track changes in oil conditions over time. As a result, users can spot unusual changes and plan maintenance work. Furthermore, Calisto 2 supports connection with suitable substation monitoring and SCADA systems. It also reduces the need for regular manual oil sampling for continuous monitoring. Thus, it supports condition-based maintenance and helps users assess transformer health over time.

The Doble Calisto 2 is an online dissolved gas analysis (DGA) monitor designed for power transformers and oil-filled electrical equipment. It measures dissolved hydrogen, carbon monoxide and moisture in transformer insulating oil. Therefore, it helps users check transformer health and identify possible problems at an early stage.
Hydrogen measurement helps detect signs of developing electrical faults. Meanwhile, carbon monoxide provides information about the condition of solid paper insulation. In addition, moisture measurement helps users track water content in transformer oil. Together, these three measurements provide useful data for transformer condition monitoring.
The monitor uses a Morgan Schaffer hydrogen measurement cell and an oil-based relative saturation sensor. Moreover, it includes built-in oil circulation and flow monitoring. Calisto 2 supports DNP3 and Modbus communication protocols. Optional IEC 61850 communication is also available. Consequently, users can connect the monitor to suitable substation control and SCADA systems. These features support continuous transformer monitoring and maintenance planning.

The Doble Calisto 2 is an online transformer monitoring instrument that combines dissolved gas detection with moisture measurement. It measures hydrogen (H2) and carbon monoxide (CO) in transformer insulating oil. Additionally, it measures moisture through an oil-immersed relative saturation (RS) sensor.
The hydrogen measurement system uses a Morgan Schaffer measurement cell. It has a measurement range of 0 to 50,000 ppm and a lower detection limit of 2 ppm. Similarly, the carbon monoxide measurement range is 0 to 100,000 ppm, with a lower detection limit of 25 ppm. These measurements help users track gas levels and identify possible changes inside transformers.
Furthermore, the instrument uses oil-immersed PTFE tubing for gas extraction. Its moisture sensor measures from 2 ppm to saturation. It also provides relative saturation readings from 2% to 100%. In addition, the monitor includes built-in oil circulation and flow monitoring. Its continuous enclosure and oil conditioning help maintain suitable operating conditions. Moreover, its vacuum-tolerant design supports use during suitable transformer dry-out and degassing operations.
The Calisto 2 Hydrogen, Moisture + Carbon Monoxide Detection Monitor uses online measurement technology to track three important transformer oil conditions. First, its hydrogen measurement system helps users identify possible electrical faults. Next, carbon monoxide measurement provides information about the condition of paper insulation. Therefore, users can monitor both electrical fault activity and insulation ageing.
In addition, the oil-immersed moisture sensor measures relative saturation in transformer oil. This helps maintenance teams understand how moisture levels change with transformer load. Moreover, built-in oil circulation and flow monitoring support the measurement process. The monitor also uses continuous enclosure and oil conditioning to maintain suitable operating conditions.
Furthermore, Calisto 2 supports DNP3 and Modbus communication. Optional IEC 61850 communication is also available. As a result, users can connect monitoring data to compatible substation and SCADA systems. Moreover, continuous measurement reduces dependence on regular manual oil sampling. The system also supports suitable transformer dry-out and degassing operations. Consequently, maintenance teams can use the collected data to check transformer health and plan maintenance work.
