The Amblyonix 1053WR Winding Resistance Ohmmeter quickly identifies loose, or improperly welded connections, missing wire strands in crimped connections, or misidentified phase relationships. The 1053WR is ideally suited for commissioning, and periodic maintenance testing, of transformers in the field. This instrument will quickly locate shorted, open, or overheated windings, and problems associated with tap-changing mechanisms.
