Electrical Winding, be it an armature, field coil or stator coil needs to be tested for various parameters prior to declaring it fit for use.Surge comparison test, High voltage Test or flash test, drop test or resistance test are the three essential tests to carry out on winding to detect faults.

Each of these was being performed manually through independent test equipment. Though this kind of test set up suited re -winders and low production units, the medium and high volume production units could not manage with this arrangement as the rate of testing was not matching the rate of production.The time taken to complete the tests on independent equipment and collection of these test data was very high as compared to the rate of production.

The industry needed test equipment, which would enable them to test the windings faster than or at least equal to the rate of production and give the result of all these tests in one place.

The Automatic Winding Test System is the result of our endeavor to give the industry what it needs the most.
