The manufacture of transformers requires engineering knowledge and skills derived from experience and from other disciplines such as chemistry, economics and user practices just to mention a few. The manufacturer’s aim is to produce equipment that is fit for purpose; that meets the purchaser’s specification and applicable Standards; that will be competitive and will enhance the business and promote furtherRead more

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 andRead more

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.Read more

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 SolidRead more

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 theseRead more

Viewing the Sea Marconi logo it is showed a stylized atom contained into a drop. These graphic elements symbolize Physics and Chemistry, red circle symbolizes energy and passion which, since 1968, lead our Research department mission, moreover blue shades represent the water as source and quality of life.During the years, the care dedicated to the Research allowed to accomplish importantRead more

(January 2006)…. While writing the presentation for Sea Marconi, we asked ourselves: who could produce a text better than the founder himself? Thus we prepared an interview and we are reporting its content here below. Marketing area D – What about the origins of SEA MARCONI R – Sea Marconi was born in Turin (Italy) on 19 December 1968. ThereRead more
