Great Transformer Repairing for You


When repairing transformers, great importance is attached to observing technological discipline, since its violation even during a separate operation can lead to a hidden defect, often not found during the repair process, but manifested in operation and caused a power outage and, therefore, causing great damage to production. Now Surplec offers the best options for the proper maintenance.

The Best Quality

The quality of repairs depends on many factors, ranging from the level of design and technological processes to individual operations performed at the workplace; from compliance by performers with technological discipline, organization and production culture, from strict adherence to standards at all stages of production.

  • The technological discipline is that each contractor strictly follows the operations established in the governing documents and their sequence, the dimensions specified in the drawings, processing modes and other conditions.


Drawings and technological documents used in the repair of transformers contain graphic and textual materials that determine the design and technological process of dismantling, assembly and restoration work. They are developed on the basis of the latest state and industry standards, enterprise standards, as well as other guiding technical materials.

A standard in the broad sense is a standard accepted as the initial one for comparing other objects with it. Standards that are normative and technical documents, depending on the scope and scope of application, establish: norms, rules, requirements, technological processes, methods and means of verification, testing and measurement, terms and definitions, indicators of product quality, labeling, transportation, storage of products and many standards with which to compare the actually obtained indicators in production.

  • Standards are divided into state, industry, republican, and enterprise standards.
  • State standards (GOSTs) are established for the most important types of large-scale and mass production. They are developed by the USSR State Committee for Standards and reviewed every 5 years.

Industry standards (OST) are established on types, types and brands of products that are not related to objects of state standardization (for example, products of serial and small-scale production of limited use). They are mandatory for all enterprises and organizations in this industry and other industries that use or consume products of this industry.

Republican standards (PCT) are established for specific types of products produced by enterprises of republican ministries and consumed (applied) within the republic.

Standards of enterprises (STP) are installed on individual parts of products and other objects used only at this enterprise.

The Proper Standards

Standards play a crucial role in the quality management system: they concentrate the efforts of the entire team (from the worker to the head of the unit) so that the technical level and high quality of the manufactured product (in our case, the transformer after repair) become everyone’s daily routine, allow rational use of material and labor resources, seek internal reserves, constantly improve professional skills, technical and cultural level of performers. The indicators laid down in the standards make it possible to correctly evaluate and stimulate the contribution of each employee to the common cause.

There are standards for quality control and technological discipline. During the inspection, they check: the compliance of products with the established requirements; the compliance of equipment, tools, industrial equipment with the installed technology, the state of jobs, the organization of warehousing of finished products and finished products, labor safety conditions, as well as compliance with drawings, operating and technological maps, standards and technological instructions.
