• TTP software's versatility provides for multiple, user defined permutations and combinations based on the type of a transformer, type of phase, type of winding, type of cooling, various rated capacities, various vector connections, and tap changers
  
• TTP software has features for different types of inspections such as final, internal, after-short-circuit, before-short-circuit, and customer witness inspection.
  
• Benefits of TTP software

  • TTP software has in-built Instrument drivers that are compatible with almost all makes and models of test 0instruments in vogue. The availability of most of the instrument drivers makes the application independent of the instrument being used for the test measurement
  • TTP software's in-built feature of automated online data acquisition from test instruments reduces the testing time and ensures error free data logging in the computer
  • TTP software's data analysis capability ensures error-free complex calculations
  • TTP software ensures error-free transformer test reports with print-on-demand facility
  • TTP software provides for easy storage and retrieval of test reports
  • TTP software has the facility of manual data entry too
  • TTP software generates auto indexing and page numbering of test reports according to the selected test sequence. It has the facility of printing test reports on A4 size blank sheets or on letter-heads
  • TTP software has simple but intuitive graphical user interface
  • Along with the detailed report format, TTP has the short report facility which gives the report of the routine test. The short report format is used to reduce the number of pages for test report
  • TTP software has the database backup facility to take the backup of database in the hard drive
  • TTP software has the facility of printing formulae sheet on demand
  • TTP software has the database backup facility to take the backup of database in the hard drive
  • TTP software provides the facility of generating MIS reports by selecting a specific period, customer, MVA, impedance and the inspection type
  • Names and makes of the instruments presently supported by the Transformer Test Pro are given in the table below. This list is being continuously expanded to include more instruments.
