- This test method covers the measurement of water present in insulating liquids by coulometric Karl Fischer titration. This test method is commonly used for test specimens below 100% relative saturation of water in oil.
- Electrical characteristics of an insulating liquid may be affected deleteriously by excessive water content. A high water content may make a dielectric liquid unsuitable for some electrical application due to deterioration of properties such as the dielectric breakdown voltage.
