Megger (AVO Biddle) MWA300 3-Phase Winding Resistance Analyzer
RENT Megger MWA300 3-Phase Winding Resistance Analyzer (Call for Availability)
The Megger MWA300 Transformer Winding Analyzer stands as a pinnacle of innovation in electrical testing, merging TTR and resistance testing into a single, efficient unit. This advanced 3-phase transformer testing system delivers comprehensive ratio, phase, and winding resistance measurements with just one 3-phase lead-set connection. No need for time-consuming reconnections—once connected, the MWA300 expertly performs DC resistance measurements across all high- and low-side windings seamlessly.
Featuring an impressive 8-terminal/6-winding resistance measurement capability, the MWA300 eliminates the necessity for interconnected boxes. This allows users to effortlessly test all six windings simultaneously, streamlining the entire testing process. Its compact "black box" design includes remote control functionality via PowerDB software, which is run on an external PC (not included).
Designed for versatility, the MWA300 series is adept at testing power and distribution transformers, current transformers (CTs), voltage transformers (VTs), as well as motors and generators. It enables quick verification of correct polarity between high and low side windings. Furthermore, to prevent issues associated with core saturation, the MWA300 comes equipped with a core demagnetization feature that safely demagnetizes the transformer core post-DC testing.
Testing Capabilities of the Megger MWA300 Include:
- 3-phase winding resistance
- OLTC/continuity (make-before-break)
- 3-phase core demagnetization
- Magnetic balance / flux distribution
- Polarity and phase angle deviation
