Dielectric dissipation factor can be termed by another names called loss factor is also accepted as the tan delta of the insulating transformer oil. When the insulating materials are located in the middle of the active section and the base section of electrical equipment, aperture current will be developed which flows through it . The insulating material which is non-conductive is offensive in nature and the current flow and therefore the flow of current through the dielectric material admirably leads the dielectric voltage by 90o.

A regular maintenance of transformer oil involves upgradation of the oil before the dissolved gases, sludge material, moisture content and the acid formation exceeds the limiting value set by the international standards. Before the effects of all the above mentioned factors overhaul ,steps should be carried out onsite to recycling transformer oil or reclamation of the transformer oil.

Power transformers are considered as important equipment of Electrical energy transmission and distribution systems. These power transformers are continuously in operation since their construction and hence their ageing process are going on towards their end of life which cannot be avoided . Due to economic factors , it is necessary to keep the current working
