Application:

The Surge tester is ideally suited for manufacturers of traction motors as it can test the single phase, three phase windings and insulation of DC armatures.

TEST POSITION I) Surge Comparison Test (Dual Channel)
At this Test Position, the windings of 1-phase & 3-phase AC induction Motor can be tested. The List is as follows:

  • 1φ & 3φ windings

  • LT coils

  • AC Stators

  • BLDC Stators

  • Alternators

  • Solenoids & Chokes

​

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.
