Sampling - Part 3
Regarding containers for Karl Fischer Moisture Analysis, SDMyers has found that a glass bottle functions as an excellent container for moisture analysis, if all of the following conditions are met: Before sampling, the capped bottle is kept dry by using a desiccant tablet; the glass bottle has a metal cap with a Teflon liner; when sampling, the bottle is filled to the very top in order to minimize the gas space in the bottle; and the KF Moisture test is the first test performed out of the bottle.
Using proper sample containers will help ensure that your samples are representative of the actual conditions inside your electrical equipment, enabling proper diagnosis to extend the life of your transformer.
