ABOUT THE TUTORIAL

Power Transformers are the vital links in the power system network. These costly systems have to function for long

periods without any problems. Any failure of these components will lead to serious consequential losses. Condition

monitoring of these equipment is essential and important to have a reliable power system network. Condition

monitoring and condition assessment of the transformer can be done by monitoring the various properties of oils.

Insulating oil having high heat transfer ef�iciency is used as coolant and insulating media in transformers and

switchgears.

The New Transformer oil before �illing into a Transformer has to undergo stringent quality tests, as per IEC 60296 and

IS 335 Standard speci�ications. Critical and basic characteristics like Density, Kinematic Viscosity, Interfacial Tension,

Flash Point, Pour Point, Electric Strength, Moisture Content, Dielectric Dissipation Factor, Speci�ic Resistance, Stability

towards oxidation, Accelerated Ageing characteristics, Sulphur content, Polycyclic Aromatics and Poly chlorinated

Biphenyls content etc. are needed to be analyzed. Similarly, the In-service Transformer oil is also required to be

analyzed as per IS 1866 or IEC 60422 standard speci�ications. The Dissolved Gas analysis of In service transformer oil

helps in �inding faults in transformers like Arcing, Sparking, Over heating or burning of solid insulation in incipient

stage itself. Estimation of Furan content in Transformer oil is useful in assessing the condition of solid insulation in the

transformer.

In Modern Rotating Machines, low fuel input with high energy throughput and high reliability are the basic guidelines.

Intricate engines with close tolerances between moving parts has become possible due to the increased ability of the

lubricants to meet these needs with the help of tailored package of additives. The functional properties such as

stability to oxidation and degradation, dispersion of sludge deposits produced in the system, modi�ication of friction in

the system, providing �luid �ilm under extreme loads, depression of pour point can be improved by special additives.

Condition monitoring in terms of condition of lubricant, wear debri analysis / elemental analysis can give information

on the abnormal degradation, wear and tear etc. to protect the machines and enhance their service life.

Petroleum reserves are scarce and are to be preserved. This is more important for a country like ours to preserve these

materials to save the costly foreign exchange reserves and also to save the environment in the long run. There is a

need to have a national policy to reclaim and reuse of petroleum products especially mineral oils in order to have

multiple bene�its of saving foreign exchange, environmental preservation and associated bene�its. The reconditioning

and reclamation is not practiced widely in the country. The technique and technology of reconditioning and

reclamation is simple in case of insulating oils and turbine oils. The program will focus on these aspects. Removal of

degradation products, �iltration under vacuum, treatment with adsorbent materials, various precautionary measures

taken up during online treatment technique are some of the aspects to deliberate upon.

Composite materials are multi-phase materials obtained by arti�icial combination of different materials in order to

attain properties that the individual component by themselves cannot attain. An example is a light weight structural

composite that is obtained by embedding continuous carbon �ibers in one or more orientation in a polymer matrix. The

�ibre provides strength and stiffness, while the polymer serves as a binder. The matrix adds toughness to the

composite. Many composite used today are at the leading edge of materials technology, with performance and costs

appropriate to ultra-demanding applications such as electrical insulation, spacecraft and aircraft.

This tutorial is being organized in �ive different modules to give an elaborate coverage of IS 335, IEC 60296, IS 1866, IEC

60422, IEC 60599 and ASTM standards of Transformer oil and Lubricating oil and to provide maintenance engineers

an in-depth understanding of maintenance of Transformer, Transformer oil and Lubricating systems. The program

consists of lectures by experts from CPRI.
