OXIDA OXID ATION ST STABIL ABILITY ITY
A key acceptance test for unused insulating oils and in-service in-service lubricant oils WHAT? Oxidation stability is the most important analysis carried out on unused insulating oils and lubricant oils to assess long-term performance during service life.
WHY? Different degradation mechanisms mechanisms at work in insulating and lubricant oil will decrease oil performance during service life and can cause equipment deterioration. If oxidation stability is insufficient, the oil should not be accepted.
