The behaviour of electrical insulation is the main parameter of its maintenance and lifetime estimation. The diagnostic is based on the knowledge of the insulating material, the measuring technique, the apparatus and the system and asset management. Tests have a defined purpose under given requirements with a clear decision and may be used as reference for the later diagnostic. Monitoring is the recording of the relevant parameters under service conditions with requirements given by the character of the recorded signal. Diagnosis is the evaluation of the signals, continuously recorded by a monitoring system, based on the knowledge of the reference value and the influence of the recorded parameters on the electrical insulating material. The weighting and judging of the parameters with mathematical algorithms allow to create a self-learning system which can be used for maintenance and lifetime estimation
