FACTORS EFFECTING ON TURBO GEN. INSULATION LIFE TIME AND HOW INSULATION AGEING TESTS DONE

Electrical insulation in turbo generators can be described as an important and sensitive part upon which the machine life time depend, for the mentioned reason it found that insulation materials which their life time completely rely on type of material used in manufacturing it also type of machine operation in power generation plants to be well introduced and well recommended. The salient subjects in this article are as follow: - Places in turbo gen. where insulation materials are used with names. - Factors which reducing insulation life time with a bfief description of the causes in power stations also necessary recommendations. - Some manufacturer insulation ageing tests, a brief comparison between some manufacturer can be observed.
