Turns Ratio Meter

Additional Product Information

Features & Benefits


  • Fully automated measurement of turns ratio, voltage ratio, phase displacement and excitation current.
  • Highest measurement accuracy in the industry of up to 0.03% makes the 2796 the perfect tool for preventive maintenance measurement
  • Automatic winding connection identification AWCI (patent pending) and automatic vector group detection supports the quick and easy operation
  • Build-in printer for quick test report generation and total prevention of data loss
  • Lightweight, compact and rugged design for use in harsh environments. Closed case is IP65 waterproof, open case is splash proof
  • Remote control software to operate the unit from a laptop PC and for easy gathering exchanging and analyzing of measurement data.
  • Ratios of up to 50000 can be measured


  • Better transformer excitation due to higher test voltage of 250V
  • Quick setup with intuitive guide-through user interface. Test setups and results can be stored and recalled, printed out with the built-in printer or used for later analysis
  • Safety connection control feature proofs test setup before applying regular test voltage to guarantee safety of the personnel and instrument.
  • Remote tap changer switch enables convenient testing of multi-tap transformers.
  • Measurement of phase displacement of transformers with irregular vector groups like: phase shifting, rectifier, arc-furnace and traction transformers.
  • Power- and distribution transformers
  • Special transformers; like phase shifting-, rectifier-, arc-furnace- and traction- transformers
  • Instrument transformers
  • IEC 61076
  • and others
