poor ventilation. In addition, the instrument will generate high voltage, so it must be used
at room temperature and in the absence of much dust.
1.1 Production introduction
Due to the influence of wire material, magnetic material, framework and manufacture technics,
winding products such as transformers, motor windings may have defects of low insulation
between winding layers, circles and leads. PT50xx series impulse winding tester, adopting
high-speed sampling techniques, is a new test instrument for insulation performance of winding
products.
PT50xx series compares the standard waveform stored in the non-volatile memory with the
current tested waveform. PT50xx series provides the PASS or FAIL comparison result according
to AREA SIZE, DIFFERENTIAL AREA, CORONA DISCHARGE or DIFFERENTIAL
PHASE. With its strong functions, accurate comparison methods, easy operation and various
interfaces, PT50xx can provide a perfect test solution for most winding products.
Principles of impulse winding test
The impulse winding tester tests the electrical characteristics of coil winding without damaging the
DUT. The prerequisite condition is to test the quality of a coil at just a glance. The detection is
carried out when the same electric impulse, as used in the standard coil and here discharged by a
capacitor, is applied to the DUT. The voltage attenuation wave 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
and 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.
Figure 1-1 Simplified diagram for principles of impulse winding test
In figure 1-2, the self-oscillation attenuation wave has a close relation with the inductance L and
quality factor Q, while L and Q depend on the number of turn, manufacture technology,
properties of iron core material and whether it has air-coils. What’s more, the applied voltage is a
high impulse voltage, thus, it is easy to observe the short circuit, partial short turns and lays or
turns discharge phenomenon caused by insulation damage.

2.2 Comparison methods
2.2.1 Area size comparison
As shown in figure 2-1, when comparison method is set to AREA SIZE, the area sizes of both
standard waveform and the tested waveform are calculated (integration method) between A and
B. The percent deviation is the ratio of the area size difference to the area size of the standard
waveform between A and B, expressed as a percentage.
Figure 2-1 Area Size Comparison
The area size of the waveform is nearly proportional to the energy loss in the winding. When a
sample winding has a short circuit between layers, the short circuit area is reflected as an
increase of energy loss.
2.2.2 Differential area comparison
When comparison method is set to Differential Area, PT50xx calculates the area size of
differential portion between the standard waveform and the tested waveform from A to B. (The
differential portion area size is indicated as the shaded part in Figure 2-2.) The percent deviation
is the ratio of the differential portion area size to the area size of the standard waveform between
A and B, expressed as a percentage.

PT5020 & PT5030 Operation Manual Chapter 2 General specifications
2-3
Figure 2-2 Differential Area Comparison
The differential area size reflects the value of inductance and total energy loss. This method is
especially effective to detect the differences of inductance L between the standard winding and
the tested winding.
2.2.3 Corona discharge comparison
When comparison method is set to Corona Discharge, PT50xx detects the high frequency energy
of corona discharge from A to B as shown in Figure 2-3. When the corona evaluation value is
less than the corona difference limit, then the comparison result will be PASS. When the corona
evaluation value is more than the corona difference limit, then the comparison result will be
FAIL. The corona evaluation value and difference limit are both expressed as an integer.
Figure 2-3 Corona Discharge Comparison
User can sample some coil samples (e.g. 10 samples) to set an effective corona discharge value.
First, applying an impulse voltage to each coil will gain the corona discharge value of each coil.
Then, a new effective value can be set by adding 20% to the maximum corona discharge value.
In order to ensure the correctness of the new value, user can test these coils once more and
observe the corona PASS or FAIL.

PT5020 & PT5030 Operation Manual Chapter 2 General specifications
2-4
2.2.4 Differential phase comparison
User can specify a zero-crossing point to compare. The instrument will judge the zero-crossing
offset between the tested waveform and standard waveform and then compare the oscillation
period between the two waveforms. The percentage of the two values will be taken as the
judging criterion and the reference is set by percentage. As is shown in figure 2-4, A~B is the
offset and C~D is the oscillation period of standard waveform. The third zero-crossing point of
the compared waveform is to set.
Figure 2-4 Phase Differential Comparison
!NOTE: The tester can only set zero-crossing points from 2 to 10. The first zero-crossing point
cannot reflect the actual performance of coils, so it is not necessary to set the first point. In real
phase differential comparison, there are four results generated: PASS, FAIL, FAIL1 and FAIL2.
PASS is up to standard; FAIL, below standard. While FAIL1 means the zero-crossing point has
not been found, that is to say, it is unable to find the set zero-crossing point on the waveform of
the tested coil; FAIL2 indicates that a complete period cannot be found on the standard
waveform. As shown in figure2-4, the third zero-crossing point must be present in the waveform
so as to ensure the normal operation of phase differential comparison.
