The development of the electric power industry and electrical machine building is associated with the use of a wide range of electrical insulating materials. The intensive development of science and technology requires the complication and improvement of the conditions set for electrical insulation. Based on the above, in order to increase the operating time of all oil electrical equipment working in the power system and have detailed information about the transformer oils to be poured and the requirements for them. The main task is to determine the requirements of standards for electrical insulating materials and compliance with technical conditions and it is advised to check by testing on the basis of regulatory documents of the quality indicators filled in them and to maintain constant control of oil equipment during operation.
