Oxidation stability test for mineral insulating oil

While some of you might recognize the outlines of the proven TC16, this is their all-new – and Tamson’s first! – six position oxidation stability bath. Mineral insulating oil needs to preserve system life, with minimal electrical conduction, acceptable heat transfer and long service intervals.

During the ASTM D2440 testing method, the oil is placed in a receptable together with a copper catalyst to stimulate the ageing of the sample. Oxygen is constantly fed through the sample, which remains in the bath for 72 or 164 hours at a steady 110°C. Afterwards, the oil is evaluated by measuring the amount of sludge and acids formed.
