Study Influence Industrial Frequency Magnetic Field On Capacitive Pressing Sensor for Large Turbogenerator Core Clamping System

In this paper a present results of the experimental study of the influence of the magnetic field of the industrial frequency on the change in the value of the capacity of the core compression sensor was obtain. The sensor is designed for the development of new types of computerized meters of mechanical defects parameters of powerful generators that can operate under strong magnetic fields of industrial frequency. Designed special stand and used it for experimental research. The experimental results of the influence of the magnetic field of the industrial frequency on the elements of the core compression sensor are obtained. It has been established that the introduction of a core compression sensor into a magnetic field of industrial frequency with a magnitude of magnetic induction from 0.1 to 0.6 T changes the value of the measured capacitance to no more than 0.8%.
