Annotation

Today, the vast majority of technological processes, both production and agriculture, are based on the use of electric machines. Among which, a significant part of production equipment requires the use of electric motors, the power of which exceeds hundreds of kilowatts. Such electric machines have also become widespread as generating equipment, where they are an integral part of power plants, both using traditional energy sources (thermal power plants, nuclear power plants, etc.), and renewable (hydroelectric power plants, wind farms, etc.), where the unit power of a single electrical machine is usually higher than in other sectors of economy.
When operating such equipment, systems for monitoring a significant number of technological parameters are often used, and in real time it characterizes the modes of their operation. This approach makes it possible to increase the reliability of operation and, with a fairly high probability, to avoid large-scale man-made threats that can be caused by an emergency failure of power electric machines (including powerful electric generators), which are quite often accompanied by the destruction of supporting structures, structural elements of industrial premises and can pose a threat to the life and health of production personnel. But the use of even the most modern systems for monitoring the technical condition does not provide one hundred percent reliability, and when operating electrical machines with a nominal power of the order of units of MW and below, their use can significantly increase the total cost of equipment with a still quite high level of occurrence of a serious man-made accident. Therefore, the development of direct methods and means for measuring the technical parameters of electrical machines in general, and insulation parameters in particular, is an urgent scientific and applied problem.
In the article was proposed a new method of direct automated measuring control of insulation of windings of an electric machine, based on the use of combined signals to determine the technical parameters of the insulation of electrical machine units. And also, the design of the measuring control has been developed, it implements the proposed method.

Keywords: insulation resistance, electrical machine, measurements, defect, active resistance, reactance.
