Testing and Maintenance Procedures for Power Transformers

MasTek provides services to the City of Riverside to standardize the testing, maintenance and diagnostic analysis of power transformers. The maintenance and testing procedures are developed in accordance with the latest IEEE standards and NETA. The testing, maintenance and diagnostic analysis of power transformers and ancillary devices such as; winding, core, surge arrestors, bushings, load tap changers, cooling systems, instrument transformers, and temperature, nitrogen and oil gauges, etc.

  • Procedure Framework Design – MasTek prepared the procedure framework, which addresses the following; Power Transformer Factory Acceptance Test (FAT), Power Transformer Commissioning Tests, Power Transformer Routine Tests (Diagnostic Tests), Transformer Test Data Analysis, Maintenance and Testing Frequency, etc.
  • Procedure and Forms Development – The testing and maintenance procedures cover power transformers and ancillary devices and equipment which estimates four procedures to be developed: Power Transformer Factory Acceptance Test (FAT), Power Transformer Commissioning Test, Power Transformer Diagnostics, and Power Transformer Scoring. MasTek developed a Maintenance and Testing Frequency report that includes the recommended interval duration for each test. Additionally, MasTek developed a maintenance and testing forms and checklists.
