Oil/Gas sampling and analysis is an effective tool to indicate both the condition of the insulation and the condition of the equipment. Unfortunately, solid insulation cannot be sampled in the same manner, so other on line technologies must be employed to evaluate equipment constructed with solid dielectrics.
