1KV Digital Armature Surge Tester
About the D-1KAT:

  • The Digital Armature Surge Tester with bar-to-bar test is a cost-effective solution to check the quality of Small to Medium range of DC Armatures. The Bar-To-Bar Test is provided to test the Low impedance of the Series wound Armatures and Field coils of DC Traction Motors. The Surge Tester has an Embedded Industrial PC with 8 inch Touch screen Display and software to Store, Recall and Print the Test Reports.

Features:

  • Infinite model storage capability

  • Job work management area for motor data reference

  • Dual feature to either store and compare against master waveform or compare between two windings simultaneously

  • Colour coded waveforms for better analysis

  • LABVIEW software to Store, print and recall surge test waveforms & reports

  • Graphical and numerical representation of %error between the waveforms

  • Automatic report generation in MS word

  • Target voltage indication based on motor ratings

Benefits:

  • Footswitch for hands free operation

  • Highly Sensitive fault detection capability

Bar-To-Bar Test for DC Armatures (Single Channel)
To perform this test, the armature to be tested is positioned between centers so that is could be rotated. A fixture with adjustable brushes is used to contact the armature at three positions. Two segments with an equal number of bars are then compared and if the two segments are balanced and contain no faults, a single pattern will appear on the Display. Faults are located by noting the change in the pattern as the armature is rotated bar-to-bar. The important advantage surge testing offers when applied to armature is the ability to locate high resistance carbon shorts. These can be major problem and cannot be detected by the low voltage tests normally done. Because the Surge tester utilizes much higher levels, these faults can be determined and located in most of the cases.
