Why to use a surge tester? (Impulse Winding Tester- IWT-5000A Introduction 1 )

Today I am going to introduce Leap's (Leaptronix's) top sell tester- IWT-5000A.
This Tester is an Impulse winding tester, which is called surge tester also.

I personally study this product the most because Thailand is my region and there are many factories there, and it is amazing that this tester is almost becoming our top sell products. 
I always remember that once a motor company from Thailand came to visit us for this machine. I was so surprised because they came to Taiwan and told us they want to visit us on the afternoon.

And I was barely prepare nothing, but fortunately, the good product is no need to introduce much, it speaks for them-self. So basically we just demonstrated it for them and answered few questions. Of course, they did not just buy it at the moment because we had to make sure IWT-5000A can actually test their products. 

So they did send two motors to us (Very heavy) for testing and it worked, then they just bought it. (Of course there were some technical questions from the customer. ) I would say that is because IWT-5000A is a very competitive product due to its surprising low price and good quality.

So if you are manufacture of motors, voltage transformer, generators, solenoid or inductance. You will need a surge tester(Impulse Winding Tester) to test the self-insulating property of the coil, so that the the defective products could be separated.


Why there are the defective products?  Below are the reasons:
  1. Layer short : The defect ( the wear off skin) of the lacquered wires, which caused brass wire to conduct.
  2. Layer insulation defect: The brass wires are not conduct, but the lacquered wires are chap and cause the corona discharge or spark discharge.
  

There are four comparison measurement to test that : AreaSize Comparison, Diffzone Comparison, Corona Amount Comparison and Corona Number Comparison.



Areasize Comparison: The total area of A-B interval can be calculated to identify the difference degree of the two areas.

   Diffzone Comparison: The area difference of A-B interval can be calculated to compare the standard wave and identify the deviation degree. 

Corona Amount Comparison and Corona Number Comparison:

•1.The test coil may discharge due to material damage, thus generating corona in the discharging curve.

•2. Statistics is made with respect to the frequency of corona generation, which called as Corona discharging number.

•3. After differential calculation, the number is Corona amount.

•4. The test volume is subject to high frequency filter.

•5.Application for discharging flutter.

In this first introduction, we just introduce who should use this machine and its testing theory.

For the coming articles, we will show how it actually works and the successful stories by our customers.
