Inspect Insulating Oil in Transformers and Bearings

Measure the specific volume resistance of insulating oil for quality control of transformers and bearings.


- Heat the insulating oil that will be tested to 80ºC and pour it into the SME-8330 Liquid Sample
- Apply a 50 V of DC current and measure the insulation resistance.
- Use a resistivity equation to obtain the specific volume resistance.

Since the SME-8330 Liquid Sample Electrode is provided with a connecting cable, it can easily be connected without having to worry about main electrodes, counter electrodes or card electrodes.
