MWA 330A 3-Phase Ratio and Winding Resistance Analyzer

An sophisticated 3-phase transformer test equipment that offers portability, a shorter setup time, enhanced job site safety, and simple productivity is the Megger MWA 330A Transformer Winding Analyzer. For a three-phase transformer, the MWA 330A offers comprehensive measurements of winding resistance, phase, and ratio.

There is only one 3-phase lead-set connection and a single instrument used for all ratio and winding resistance testing. With just one setup and one user-friendly test form, the MWA 330A saves the user even more time by using PowerDB as a single software platform.

FEATURES AND BENEFITS

  • “One-time” 3-phase connection tests all six windings for faster and safer testing.
  • There is no need for a switchbox, making operation simpler and safer.
  • Special Kelvin clamps with innovative adjustable jaws that each open to 100 mm (4 in.) and the ability to connect to terminal blocks using a banana plug eliminate the need for specialized lead sets and reduce operator mistake caused by lead connections.
  • A bright-color, industrial-grade 305 mm (12 in.) touch-screen display is an optional feature. Results and reports are carefully stored, and it can be used in tough conditions and intense sunlight without the need for IT intervention.
  • Checks the contact and timing health of LTC (OLTC) tap changers.
  • It is usual practice to test LTCs by one person when using an optional remote tap controller (RTC-1).
  • PC connectivity via USB for convenient remote control operation and test result downloads.

The MWA3xx effectively tests:

  • Power transformers
  • Distribution transformers
  • CTs and VTs (PTs)
  • Motors/generators

TESTING PERFORMED:
