Product Overview

HAEFELY / HIPOTRONICS TTR2795 TRANSFORMER TURNS RATIO METER (Call for Availability)

The Haefely / Hipotronics TTR2795 Transformer Turns Ratio Meter uniquely combines winding resistance measurement, turns ratio measurement, core demagnetisation, transformer type detection and heat run test (cooling curve) in one extremely fast instrument. A simple one-time-connect-all system drastically reduces measureing time. Once connected all tests can be done in a row without any reconnection.

Features and Specifications of the Haefely / Hipotronics TTR2795 Transformer Turns Ratio Meter include:

Features:

  • Fully automated measurement of turns ratio, voltage ratio, phase displacement and excitation current
  • Automatic winding connection identification (AWCI) and automatic vector group detection provide quick and easy operation
  • Safety connection control feature proofs test setup before applying test voltage to avoid any damage of personnel, test equipment and instrument
  • Built-in printer for quick test report generation and total prevention of data loss
  • User friendly self-explaining interface with one rotary-push-button for easy access to the menu structure
