HAEFELY WA 2293 Automatic Transformer Winding Analyser
The WA 2293 is an automatic winding analyser, optimized for three phase power and distribution transformer measurements.
It 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 without needing to reconnect
