In the current times of dominance of technology and scientific and technological progress, there are increased requirements for the latest materials, individual devices and large products. In view of this, these items are tested for a variety of mechanical, climatic, and electrical tests. And here one cannot do without special equipment, which is used for these purposes. A large number of test electrical equipment is presented on the website of the Joint Stock Company "Electroapparat" www.apparat.su
Consider the cases when you have to deal with electrical tests :
- it is difficult to imagine any branch of the economy where electrical equipment is not used, which means that to check the simplest and very complex equipment, whole test benches are created, where many various programs for checking the condition of this equipment are laid down at various values of voltage and current in the circuits of the tested product;
- modern communications are not possible without all sorts of cables, for checking and troubleshooting, such measuring devices as generators and receivers of audio frequency are used to determine the cable route and damage to them, as well as devices for closing the sheath cable to ground, high-voltage acoustic stands, digital reflectometers, stands for burning defective cable insulation;
- devices for checking automatic switches are designed to measure the hour and amplitude characteristics of these devices;
- test equipment for checking high-voltage arresters to determine the breakdown voltage;
- devices for testing the characteristics of insulating liquids, such as breakdown voltage, dielectric loss tangent, electrical capacitance;
- any electrical equipment is checked for testing the insulation of power cables;
- devices for testing electrical protection equipment used in electrical installations, such as dielectric gloves, galoshes, etc .;
- modern medicine cannot exist without all sorts of electrical devices that affect various parts of the human body;
- and many others that are used in various sectors of the economy.
All these test devices and just electrical equipment share common electrical parameters:
- the magnitude of the acting voltage and current;
- for alternating voltages, the frequency of the signal, which varies from audio values to optical values.
Modern electrical equipment can generate many signals of various shapes and the ability to adjust both manual and automatic amplitude and phase values. Thus, it becomes versatile for various tests.
