Sustainable Electric Power for Emerging Markets, Part 1

Many developing countries experience either a lack of dependable power or suffer through countless periods of blackouts. The reasons vary from vandalism to theft of insulating oil, but stem most often from poor or non-existent maintenance and security of the existing power grid. The consequence is often the complete destruction of transformers. A comprehensive maintenance and security program for transformers can prevent this.

Transformer Oil, Part 1: Maintenance of Mineral Transformer Oil

Cover of the Transformer Oil, Part 1: Maintenance of Mineral Transformer Oil white paperThe function of transformer oil is insulation and cooling of transformers. A transformer consists of metal, oil, and cardboard insulation. The oil is actually insulating oil and is used not only in transformers, but also in circuit breakers, capacitors, bushings, and tap changers. Insulating oil is a refined mineral oil obtained from fractional distillation of crude oil. It is free of moisture, inorganic acids, alkali, sulfur, asphalt, tar, and vegetable or animal oils.
