Application Note: Moisture in Insulating Oil using the Mitsubishi CA31 Coulometric Karl Fischer

We have produced a new application note focused on moisture in insulating oil utilising the Mitsubishi CA31 Coulometric Karl Fischer from a1-envirosciences GmbH.

Coulometric Karl Fischer

The coulometric Karl Fischer method is the preferred method for determination of moisture in insulating oil. It is a standard technique with high accuracy and precision and can detect moisture in the oil to 0.5 ppm, which is well below requirement for maintenance and specification for supply of unused oil.

Mitsubishi/Nittoseiko CA31

The Mitsubishi CA31 Moisture meter is a coulometric Karl Fischer designed for both lab and mobile transformer oil analysis as it can be configured as either a mains or battery powered unit. Results from the CA31 are displayed on the touch screen interface automatically as weight of moisture in a known volume oil sample.

Conclusions

Condition monitoring of both transformer oil and synthetic transformer oil is crucial to the national power network. Coulometric Karl Fischer is the preferred solution for measuring the moisture content of transformer oils. The data presented here demonstrates that the Mitsubishi/Nittoseiko CA31 is the ideal solution for both lab and field based analysis.
