IMPULSE WINDING TESTER
( WINDING
/ LAYER SHORT TESTER FOR ANY COILS )
|

WINDING / LAYER
SHORT TESTER FOR ANY COILS |
The
impulse winding tester tests the electrical characteristics of coil winding
without damaging the DUT. The prerequisite conditions for quality of a coil
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.
Brief Introduction
:
Due
to the influence of coil wire material, magnetic material, framework and
manufacture techniques etc., coil products (such as transformers, motors, etc.)
may have defects of low insulation between coil layers, circles and leads.
VE2882 series impulse winding tester, adopting high-speed sampling technique, is
a new generation analysis test instrument for insulation performance of coil
products.
When
testing, VE2882 compares the standard waveform stored in the instrument with
current measuring waveform. TH2828 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, VE2882 can provide test solution for most coil winding products
