Product Details

The Haefely 2293 is an automatic winding analyzer, optimized for three-phase power and distribution transformer measurements.

 

The Haefely 2293 Automatic Transformer Winding Analyzer uniquely combines winding resistance measurement, turns ratio, dynamic resistance measurement, core demagnetization, transformer type detection, magnetic balance, short circuit impedance and heat run test (temperature rise and cooling curve) in the fastest single instrument solution on the market.

 

A simple “one-time-connection” system drastically reduces measuring time: once connected all tests can be performed in a row without any reconnection.

 

The built-in simultaneous winding magnetization method guarantees fast and reliable resistance measurements. Stable measurements are reached even on large power transformers with delta windings on the low voltage side.

 

A progressive method for measuring transformer turns ratio guarantees results closer to the nominal ratio even in large power transformers with tertiary windings.
