2882A-3 Transformer,Motor And Winding Test Instruments Impluse Winding Tester
When testing, TH2882A compares the standard waveform stored in the
instrument with current measuring waveform. TH2882A gives the PASS
or FAIL comparison result according to Area,Differential Area,
Corona Discharge, Differential Phase etc. With strong function,
precision test method, flexible operation and various interfaces,
TH2882A can provide test solution for most coil winding products

Brief Introduction
■ Due to the influence of coil wire material,magnetic
material,framework and manufacture technics etc ., coil products
(such as transformers, motors, etc.) may have defects of low
insulation between coil layers,circles and leads. TH2882A series
impulse winding tester,adopting highspeed sampling technique, is a
new generation analysis test instrument for insulation performace
of coil products. When testing, TH2882A compares the standard
waveform stored in the instrument with current measuring waveform.
TH2882A gives the PASS or FAIL comparison result according to
Area,Differential Area, Corona Discharge, Differential Phase etc.
With strong function, precision test method, flexible operation and
various interfaces, TH2882A can provide test solution for most coil
winding products.Theory of Impulse Test of Coil-winding
■ The impulse winding tester tests the electrical characteristics
of coil winding without damaging the DUT. The prerequisite
conditions for quality of a coil can be detected at just a glance.
The detection is carried out when the same electric impulse by
capacitor discharge is applied to the standard and the DUT. The
voltage decay waveform is generated in response to the impulse,
related to the Q-factor and inductance of the coil. In this sense,
the tester can detect turn & layer short, the differences in
the number of turns and the material of the core. If high impulse
voltage is applied, the poor insulation will appear as a corona or
layer discharge.
