Transformer maintenance

The life of a transformer consists of many steps from initial specification, design and manufacture through installation, operation, maintenance, and possible change of state with reconditioning and, eventually, replacement. A model of the life of a transformer may be presented as a change of its condition, namely as reduction of safety margin with time under impact of thermal, electric, electromagnetic and

Insulating oil regeneration and PCB destruction

Insulating mineral liquids can be regenerated to prolong their lifetime and avoid failure of the transformer. The regeneration removes unwanted degradation products from the oil. This paper gives a background to the effects of degradation products, transformer monitoring and ways of removing of unwanted products.PCB is discussed as a special case with a background to the legislation and health aspects.

Degradation and chemiometryc models

Considering the difficulty in taking samples of insulating paper of transformers, the evaluation of the degradation of cellulose through the analysis of the products of its degradation (furans) dissolved in the oil has been pursued. The furans are formed by the ends of the polymeric chain of cellulose. Insulating materials in transformers are of two types: Fluid insulation: oil Solid

Revised IEC standards for supply and maintenance of insulating oil

The international organization responsible for producing standards for electrical material is International Electro Commission (IEC) and member countries have their own national committee. Liaison is maintained with International Standards Organization (ISO) to prevent duplication in borderline area of mutual interest. Within IEC, Technical committee 10 (TC10) is responsible for fluid for electrical application, which covers over 46 standards. Among these
