3KV Digital Armature Surge Tester


TEST POSITION I) Testing of Stator and Field Coils of DC Armatures (Dual Channel)
This tester is widely used in Railways and Diesel Local sheds for Testing Newly and Rewound DC Traction Motors. The High Pulse current and Pulse Energy is ideally suited to Test the Field and Pole Coils of DC Motor and also completely wound stator with the help of 3-phase Test Select Switch.

  • Stators Of DC Traction Motor
  • Field And Pole Coils

TEST POSITION II) 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.
