Description:

Because of the influence of coil wire material, magnetic material, framework and process craft etc., 

coil product (such as transformer, motor…etc.) can generate debasement of the insulation performance 

of the coil layer, circle and down-lead. TH2882A-5 impulse winding tester, adopting high-speed sampling

technique to develop, is a new analysis test instrument for insulation performance of coil product. Memorizing 

sampling waveform of standard coil winding in the instrument inside, when testing, TH2882A-5 compares standard 

waveform and tested waveform according to criterion of settings (Area, Differential Area, 

Corona Discharge, Differential Phase etc. ), then judges if the coil winding is good or bad. This instrument gathers 

mighty function, precision testing method, flexible operation method and various interfaces to offer test solution for 

most coil winding manufactories. The product saves sampling waveform of standard winding in instrument, and compares 

measured waveform with standard one at the time of measurement. The measured winding will be judged according to set 

criterion (area, area difference, phase difference, corona). TH2882A-5 is mainly used to measure three-phase 3-wire or 

three-phase 4 wire motor with three windings. Measured waveform is compared with standard one in instrument, or different waveforms in 

different windings are compared without standard waveform.

Feature:

 Low inductance impulse test: down to 10μH

 Low energy test without damaging the coil

 Fast detection of winding insulation at a speed of 5.5 meas/sec
 4 kinds of waveform comparison methods
 Up to 40 MSPS sampling rate
 320×240 dot-matrix graphic LCD display

 Multi-trigger mode programmable
 Voltage, Time and Frequency measuring function
 Direct display of comparison result
 Keyboard lock and password protection function
 Handler, RS-232C, and GPIB(optional) interfaces
 500 groups of waveforms can be stored in USB disk

(optional)
 Multi-channel scan control interface: SCANNER (optional)
