This advanced 3-phase transformer test system provides complete ratio, phase and winding resistance measurements with only one 3-phase lead-set connection. What’s more, it offers portability, a reduced set-up time and increased job safety.

Once connected, the MWA300 performs DC resistance measurements on all high- and low-side windings without reconnection. It has an 8-terminal/6-winding resistance measurement capability and doesn’t need any inter-connected boxes, allowing you to test all 6 windings without having to disconnect and reconnect leads.

The MWA300 series saves you even more time by using a single software platform, PowerDB, which means you only need one set-up and one easy-to-use test form.

The MWA300 series can be used effectively test power transformers, distribution transformers, CTs and VTs, and motors and generators

The following tests are easily performed with a single instrument, the MWA300 series, and a single 3-phase lead set connection:

  • 3-phase turns ratio
  • 3-phase winding resistance
  • OLTC continuity (make-before-break)
  • 3 phase core demagnetization
  • Magnetic balance / flux distribution
  • Excitation current
  • Polarity and phase angle deviation
  • Auto vector detection
  • Heat-run test
