Power/Distribution Transformer Test System

TrafoTest Premium and TrafoTest Compact

ONE operation interface for the COMPLETE LAB

These systems are a revolution in the fully automatic testing of power and distribution transformers. A complete new development using state of the art intuitive software, operated over a big touch screen monitor offers unique user comfort. The accuracy of the system is unmatched, especially at low power factor by using EPRO's standard voltage and current transformers.

Main Features:

  • TrafoTest Premium: System with two big screens, one for operation and one for display of results
  • TrafoTest Compact: System with one big touch screen for operation and display of results
  • Suitable for routine tests and scientific tests
  • Ideal for use in power/distribution transformer factories
  • Tests done according to the latest IEEE and IEC standards
    • Load loss test
    • No load loss test
    • Induced overvoltage test
    • Zero sequence impedance test
    • Temperature rise test (Heat run test)
