Nowadays the technical condition of power transformers is estimated by a large number of standardized parameters. We will conduct a comprehensive assessment of the condition of the transformer equipment.
The purpose of diagnostic tests is to check certain parameters of the transformer, which are characteristic of it's condition. Diagnostic tests will help to determine the condition of the transformer and choose the right adjustment methods that will increase the reliability and extend transformer's service life.
Departments of SEC "ZTZ-Service"
Comprehensive diagnostics of the state of transformer equipment, based on both traditional measurements and tests, and special measurements and inspections, which contain a complete analysis of the oil on the 24 indicators.
The program of complex diagnostics is developed on the basis of an estimation of a design and individual functional equipment systems.
Assessment of equipment's ability to work
Determining the type, cause and danger of the defect
Determining the need and scope of repairs, mapping defects and malfunctions
Technical support of equipment operation in the presence of signs of defect
Determination of the degree of deterioration and technical condition in order to extend the service life
Development of recommendations for improving operating conditions
Field testing lab
The main task of the field testing laboratory is to obtain objective and reliable information about the insulating, electromagnetic and mechanical systems of power and measuring transformers, shunt reactors, in order to assess their technical condition.
The laboratory is accredited in the certification system of Ukraine.
The work performed by the laboratory is part of a comprehensive inspection and diagnostics of transformer equipment.
High-performance, accurate and noise-tolerant test rigs and measuring systems are used to perform measurements:
Insulation analyzer М4000 by "Doblе", USA
Facility for transformers testing СРС 100 by «Omicron», Austria
Teraohmmeter МI 2077 by «Metrel», Slovenia
Partial discharge measuring complex of UPDA type by «Cutler-Hammer», USA
Multimeters: UNIGOR 390, PowerLogger 10 by «LEM», Germany
