    IntroductionVisual Inspection of Power TransformerTransformer Diagnostic and MonitoringSchedule of Preventive Maintenance Actions and Inspection of TransformerOil Analysis and SamplesTransformer Tests For Maintenance & Diagnoses PurposesInfrared ThermographyBeing transformers static machines without any moving and turning parts, they are very reliable machines, and if maintained properly, can last for 40 years or more. Also they do not trip or blow when oven-stressed (except under extreme conditions), transformers are frequently overloaded and allowed to operate well beyond its capacity. However, use and ageing of electrical installations, similar to other installations, is an origin of normal deterioration in electrical equipment that can be accelerated by factors such as a hostile environment, overload, or severe duty cycle. Other causes of deterioration may be load changes/additions, circuit changes, improperly set/selected protective devices and changing voltage conditions. However, equipment failure is not inevitable if a checking and preventive maintenance programis established. 1.

    Also, SF 6 in the oil can complicate the Dissolved Gas Analysis (DGA) processes that are so important to transformer health assessment and maintenance decisions. For example, dissolved SF 6 will cause some DGA monitors and portable analysers that use IR measurement methods (e.g. Photo Acoustic Spectroscopy, Non-Dispersive IR) to report false high readings for one or more key fault gases.
