Chapter 1 Overview

Thank you for your Choosing one of our products. Before the use of it, please locate the items

listed in this manual to ensure nothing is missing. If in the case that any item is missing, please

It is necessary to read this manual carefully before your proper use of PT50xx series impulse

winding tester.

Warning!

1) Operation

Do not put heavy objects on the tester.

There is a cooling fan on the rear side of this instrument, so any block of the air inlet is

prohibited.

2) Rigid power input

The stability of high voltage depends on stable power input. Be sure to provide rated AC

power or corrected power.

3) Grounding

For the safety of personnel and instrument, ensure the grounding terminal, designed in

power cord, be grounded correctly.

4) Test cable

To avoid electrical shock hazard, do not touch test terminals and test samples. The reason

is that a high voltage test cable is connected to the rear panel of this instrument, thus when

testing, the cable and test samples connected will carry a high voltage.

5) DO NOT open case unauthorized!

To avoid the injury to personnel and damage to the instrument, do not open the case

unauthorized due to the existence of high voltage in instrument.

6) Carry or move

Before moving the instrument, unplug the AC power sockets and remove high voltage test

line or external control line.

7) Maintenance

In non-use state, the instrument should be covered with a plastic or cloth cover. To clean

the tester, wipe the dirty parts with a soft cloth socked with diluted neutral detergent. Do

not use the following chemicals to clean the instrument: diluent, benzene or organic

solvent with similar chemical property with above materials.

8) Location

Do not locate the instrument in the environment of high temperature, direct sunlight or

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.
