the power transformer is a vital part of any distribution network in india and worldwide. Significant numbers or indeed have exceeded there 40 years design life. 1.power transformers may be slowly moistened over the years or be quickly moistened when repairing some faults.
2. As paper moisture content rises the rate of ageing increases and dialectic strength falls , ultimately paper become brittle and fails.
3.decomposition product in transformer like paper, pressboard and wood in the cellulose de-polymerization is water which is store in the insulation and also in transformer oil. 10% of the weight of power transformers reduces dielectric margin, decreases partial-discharge inception voltage, debases insulation performance and increases the probability of unexpected failures.
4.the condition of the paper is indicated by the degree of polymerization or dp. The higher the dp, the longer the length of the cellulose hydrocarbon chain and the better the condition of the paper. New paper typically has a dp value of around 1800. As the cellulose ages, it breaks down into smaller lengths i.e. The dp value falls. Critical dp values are around 200-300,
5. If a transformer is to have extended service life then internally generated moisture and free fibres must be continuously removed.
6. The best method of removing water from a power transformer is to undertake a mobile vapour phase dry-out at the transformer manufacturer using hot kerosene at 150-180oc to remove oil and water from the insulating papers.

Atmospheric drying is carried out for transformers with a working voltage of 33kv. In higher voltage class transformers thicker and longer insulation parts are used. Ordinary air drying will not be able to remove moisture contained in this insulation within a reasonable time. Therefore vacuum drying is used for such transformers. Vacuum drying also accelerates the drying speed.
at normal atmospheric pressure boiling point of water is 100 deg c. But in vacuum water boils at very low temperatures. Following details are given to get an idea of relation between pressure and boiling point of water.
pressure boiling point
760mm/hg 100 deg c
4mm/hg 1. 24 deg c
1mm/hg -19 deg c
vacuum drying autoclave
simply placing transformer in autoclave vessel under vacuum will not remove moisture form that. For evaporating water into steam latent heat of water is to be supplied.
when transformer put in to the autoclave for drying heat energy is transferred to transformer via convection and radiation. Compared to convection energy transfer by radiation is very low. During vacuum drying as air is sucked out there will not be any transfer of heat by convection. This necessitates heating by hot air of sufficient duration, before vacuum drying in the autoclave vessel by externally either by thermic fluid heating system/electric heating system/steam heating by means of radiator coils inside autoclave or limpets welded outside the autoclave.

It is generally used to convey low to high density, non-abrasive and semi-abrasive materials. Examples include Bleaching Earth, sugar, ironoxide, titanium dioxide, silica flour, cement, and limestone.
The material is fed into the conveying line on a continuous basis by vacuum. Air Saver technology is used to minimize and optimize the low pressure supply air which is supplied by a low pressure positive displacement blower. The system includes a vacuum pickup nozzle, a vacuum filter receiver, a rotary airlock feeder and a positive displacement blower.
The Pressure Concept Conveying System is a dilute phase, low pressure, high velocity, continuous
conveying system. It is generally used for conveying low to medium density, and non-abrasive bulk solids where degradation of the conveyed material is not a concern. Examples of materials include flour, sugar, salt, grain, malt and plastic pellets.
