Details

New 3-Phase Ratio and Winding Resistance Analyzer from Megger

  • Combines TTR and resistance testing in one box - faster, more efficient testing
  • 55% smaller, 40% lighter than individual instruments
  • Only one set of leads required - lighter, smaller and less expensive
  • One test form - easier, faster to complete
  • Built-in demagnetization

The Megger MWA3xx Transformer Winding Analyzer is an advanced 3-phase transformer test system delivering portability, reduced set-up time, increased job-site safety, and effortless productivity. The MWA3xx provides complete ratio, phase and winding resistance measurements for a 3-phase transformer. All ratio and winding resistance tests are performed in one instrument, with only one 3-phase lead-set connection. The MWA3xx utilizes PowerDB as a single software platform saving the user additional time with only one set-up and one easy-to-use test form.


Testing Performed:

  • 3-phase turns ratio
  • 3-phase winding resistence
  • OLTC/continuity 
  • 3-phase core demagnetization
  • Excitation Current
  • Polarity and phase angle deviation
  • Auto vector detection
  • Heat-run test

Once connected, the MWA3xx performs DC resistance measurements on all high- and low-side windings without reconnection. The test procedure is simple and efficient. Delivering eight-terminal/six-winding resistance measurement capability without the need for inter-connect boxes saves the user time by testing all six windings without having to disconnect and reconnect leads.
