IWT-5000A - 5KV Surge Tester / Impulse Winding Tester

surge tester, impulse winding tester

Introduction
 
IWT-5000A surge tester / impulse winding tester is a coil (such as voltage transformer, inductor, motor, power choke) turn to turn insulation testing instrument that implement surge test for self-insulating property of the coil with impulse surge voltage. The influences of winding materials, magnetic materials, and framework, also extra fabrication decreases the insulating property of coil layers along with the jumpers and jacks. Based on IEEE 522 standards, Surge Testing for turn to turn insulation is a must and thus surge tester has been widely applied in winding factories to ensure the quality of magnetic coils for transformer, stator, motor, inductor, electric valve and other automotive parts.

The IWT-5000A impulse winding surge tester adopts the technology of high-speed sampling rate to store the sample waveform of the standard (master) coil in the instrument. By comparing the waveform results of the test coil to the master, the defect in the DUT can be found easily. Moreover, IWT-5000A surge tester judges the quality of the testing coil according to the parameter set by the user.

Features
  • With 200V~5000V programmable impulse voltage, the surge tester is capable of low-energy testing, without damaging the coil.
  • Provides high-speed sampling rate of 100MHz, which enhances the testing ability for partial discharges.
  • 320 x 234 color LCD display clearly for the user to view waveform and test results.
  • Provides user-friendly operation interface.
  • Low inductance during impulse testing, minimum to 10uH.
  • Provides 4 kinds of detection modes: AreaSize Comparison, DiffZone Comparison, Corona Amount Comparison, and Corona Number Comparison.
  • The comparative result shows Pass/Fail directly, informing operators the detect test result within a short period of time.
  • Offers measurement functions for voltages, timing and frequencies, which provide user a carry-out analysis in detail.
  • Able to save 360 sets of standard waveform result of the winding coil for users to download and implement into testing.
  • Provides RS-232 to PC connection. Just using standard text command, you can write control program and data for communication easily. It's the best way to set up the testing system for mass production.
  • To make analysis easier, IWT-5000A impulse winding tester offers USB 2.0 interface to connect with PC for users to upload or download the parameters of waveforms results.
  • Provides the control function for external I/O, such as the Handler adopts standard D-SUB 15-pin connector for connecting with automatic or semi-auto testing system.
