  • Dielectric properties of natural esters and their influence on transformer insulation system design and performance — An update

    There is considerable knowledge of transformer insulation system design based on the use of cellulose insulation used in conjunction with mineral oil. This knowledge is based on over 100 years of transformer design and manufacture. Insulation design is based on the stress distribution between the solid insulation, in this case Kraft, and the fluid. In power and distribution transformers the stress is distributed in accordance with the permittivity of the various insulation components. The insulation designer must determine the stress in the fluid, in the solid insulation and along the interface. Design curves have been established for mineral oil, which give limits to the allowable stress at each of these critical areas. This paper presents the results of a test program to develop these criteria for Kraft insulation in natural ester fluids. This paper is an update to a paper presented at the IEEE T&D Conference in Dallas Texas in 2006. At that time we had not completed all of the dielectric tests. These have now been completed and are presented in this paper.

  • Gases dissolved in natural ester fluids under thermal faults in transformers

    Natural ester fluids are biodegradable and fire-resistant liquid dielectrics which have been used in power transformers in recent years. This paper presents the results of an experiment to simulate typical thermal faults in power transformers. The temperatures of thermal faults ranges from 90°C to 800°C. Dissolved gases in natural ester fluids under the thermal faults were investigated. The experiment results show that the characteristic gases dissolved in natural ester fluids differ from those in mineral insulating oils under the thermal faults. The criteria of the three-ratio method in the IEC standard for the traditional dissolved gas analysis (DGA) are not suitable for fault diagnosis of transformers filled with natural ester fluid.

  • The Characteristics of Winding Temperature for the Natural Ester Filled Transformer up to and Including 500 kVA

    Because of environmental friendly and higher fire point, Natural ester fluids are widely used for transformer cooling materials. Natural ester has higher viscosity than that mineral oil. Top oil temperature and hottest temperature will be warmer when using natural ester fluid in transformers designed for conventional transformer oil. Although natural ester has less influence on deterioration of cellulose paper than mineral oil, an increased hottest temperature might have an effect on the aging of insulating paper in coil winding. When comparing natural ester with mineral oil at the same designed transformers up to 500 kVA. The deviation of hottest temperature between the two is increased with load. For preventing additional aging of insulation paper, design changes are required when substituting natural ester for conventional transformer oil.
