The actual problem is the diagnosis and monitoring of the technical condition of the machines in operation, as well as the forecasting of their technical condition. The complexity of the problem of condition controlling is that the most informative characteristics of the electrical products can not be accurately determined without the use of special measuring transducers, which considerably increases the test time and makes it difficult to carry out continuous monitoring. A promising direction in solving this problem is the use of sensorless methods. Implementing these methods is based on using as a source of information the working winding of the electrical product, the active component of the resistance of which is determined just before the measurement of the magnetic characteristic and then used as a constant value. In the process of testing, there is heating and, as a consequence, a change in the active component of the winding resistance, which causes an unacceptable errors in determining the electrical products state. In this article the mathematical model of thermal processes are developed and analysis of thermometric diagnostics of electrical products is carried out.
