Universal breakdown installation, or, as it is also called, UPU, is an almost indispensable device, especially when it is necessary to work with electrical equipment. The use of the UPA is a guarantee of safety in any start-up of an electric machine, which is characterized by very high voltage, as well as very high power.

General Description of TOS

If we talk about the general purpose of these installations, they are used in order to carry out systematic and stable tests of the existing insulation of electrical equipment. In addition, you can also check electrical materials. The test is carried out by adjusting the alternating current of the given parameters in the selected range.

For those who are not too well versed in the breakdown installation and in this matter, it is enough to know that consultants in the store can also select certain characteristics of this device. It is only important to explain exactly why the device is being purchased, as well as any otheradditional information about the test object.

Use area

It is worth noting that, for the most part, punching installations are used in two large areas of human life. The first sphere is connected with energy, that is, the energy market, and the second with electrical products, this sphere includes everything else that does not concern energy. This versatile equipment perfectly copes with all tasks in one area and in another.

However, it is worth noting that there is another area of use of universal breakdown installations. A separate category includes scientific and research and production electrical laboratories. Most often in such places they are engaged in the manufacture of some kind of experimental electrical equipment. Working with the breakdown unit UPU is also connected with the fact that it is designed to reduce the risk that appears due to the fact that high voltage and operating power of the tested devices are used for work. Timely inspections of the insulation of equipment already in operation also play a significant role not only in maintaining the he alth of personnel, but also in preventing the failure of expensive equipment. Quite often it happens that some equipment is created in a single copy and is used to perform specific tasks in the chosen direction.

In any case, it is necessary to study the manual for the test installation (thisinstructions for the use of safety equipment, which is the UPU). It can be added that the universal installation can be used to check not only equipment, but also, for example, rubber gloves or boots for the possibility of conducting an electric current through them.

Installation of UPU-10M

High-voltage measuring UPU-10 breakdown unit is intended mainly for generating voltage of direct and alternating sinusoidal current, the frequency of which is 50 Hz. In addition, it is also excellent for measuring both AC and DC voltage and current when testing or diagnosing insulating cables.

Features and Specifications

With regard to certain features and benefits of this TOS, they are as follows:

• all voltage and current measurements are made with high accuracy;
• a built-in discharge device is available, which can be used if you need to remove the charge from the capacitive device;
• the device is capable of automatically switching AC / DC if necessary;
• working mode can also be manual or automatic and there is a timer;
• the control interface is quite simple and clear, and the graphic display is large;
• there is an intelligent limitation of the charging current to avoid the breakdown of the capacitive load of the equipment;
• The weight of the device is relatively low at only 18.5kg.

The measuring range of AC sinusoidal voltage is from 0.10 kV to 10.00 kV. The same range is present when measuring voltage with a negative polarity. The measurement range for RMS current and normal current is also the same, from 0.03mA to 10.00mA.

Purpose and features of UPU-1M

As for the UPU-1M test unit, it is intended for testing the insulation of electrical equipment and materials. For testing, an alternating sinusoidal electric current with a frequency of 50 Hz is used. In addition, a negative polarity rectified voltage can be used, which is adjustable from 0-6 kV, and the output current is 0-100 mA.

As for the features and benefits, here we can say that this model has the same qualities as the UPU-10M. It also stands out for high accuracy, automatic switching of the operating mode, intelligent charge limitation, and a built-in discharge device. Even the weight of the device remained the same and is 18.5 kg.

Special specifications.

1. Average service life is 5 years.
2. MTBF under normal conditions of use is at least 8000 hours.
3. The normal power supply for this unit is 220V ± 22V and 50Hz ± 10Hz.
4. The maximum power this appliance can draw is 900 VA.
5. Dimensions UPU-1M - 360 x 155 x 395 mm.

TOS GPT

You can consider the GPT breakdown installation using the example of model 79901. This device is multifunctional. The AC breakdown test can be performed from 100 V to 5 kV in 2 V steps. It is possible to measure the leakage current from 2 to 200 mA, while the DC leakage current can be measured from 2 to 40 mA. The instrument is capable of displaying a graphical representation of the results obtained after the test.

Features and installation options

It's worth starting with the fact that the output power of this device is 500 VA. As already mentioned above, the device displays a graphical display of test results, and also has output amplifiers with PWM technology. It is possible to record, as well as subsequent automatic playback of profiles. The number of saved profiles is 100 cells. The liquid crystal display is just designed to display graphic images.

This model differs significantly from others in that it has a very high level of protection. There is a "Self test / cutoff" mode of the output voltage in just 150 µs and several other functions. During the test, the device also regulates too high a voltage. As for the adjustable voltage rise time, it takes from 0.1 to 999.9 s. Redundant output connectors are located on the rear panel of the instrument. There is a possibility of remote control as well as regulation. ATAt the end, you can also add that this device weighs almost 10 kg more than the UPU-1M - 27 kg.

Conclusion

Summing up, we can say that universal punching installations are quite powerful and good equipment, which has not been widely used in vain. Most power and electrical equipment tests can be carried out with these units, and the accuracy of these tests is always quite high.

The quality of these devices is also evidenced by a large number of positive reviews. It is noted that all the listed advantages and characteristics of the devices are true. The only drawback, according to buyers, is that it is quite difficult to deal with this device, especially if a person does not have certain knowledge in electrical engineering.
