TPS Equipment & Reporting

Our experienced field technicians utilize state-of-the-art equipment with old fashion training to deliver reliable results quickly and accurately.

Our equipment includes:

  • Manta MTS-5000 and MTS-5100 relay test equipment
  • RTS automated relay test software for static testing of relays and dynamic testing for complex relay schemes and end-to-end testing.
  • Automated CT test sets to reproduce factory tests in the field
  • Automated TTR to reduce time and capture data accurately
  • Automated Power Factor test sets
  • VLF hipots with tan delta, automated via bluetooth to capture data safely
  • All data collected is stored in our test sheet database PowerDB.

Test Result Collection & Storage

TPS uses PowerDB Reporting Software to collect and store information. PowerDB specifically allows for the collection and reporting of data from maintenance and inspection activities performed on equipment used in the generation, transmission, and distribution of electric power. The software includes interfaces for many common test instruments and allows for automated testing and data acquisition, as well as imports from various file formats. Result and summary reports can be easily generated. Most of our test sets integrate directly or indirectly with PowerDB.

PowerDB Reporting Software provides:

  • Data Trending for Predictive Failure Analysis
  • Electronically Delivered Reports
  • Deficiency Summary Reports
  • Test Instrument Data Acquisition
  • Data Replication through DB Syncing

Benefits include:

  • Consistent report layouts
  • Faster report generation
  • Faster collection of information
  • More accurate collection of information by removing human error
  • Long-term storage and instant access to customers’ data
  • No searching for the results from the last test as we already have the data
