ERROR DETERMINATION OF RANGE-VERIFIED FERROMAGNETIC CURRENT TRANSFORMERS

Increasing the reliability of ferromagnetic current transducers, the range of which is adjusted. During the trial period, the defunct FMTO was not replaced by a new one. Total trial period T0=200·103s during this period, the isolation of the lungs, the failure of their input and output parts, and the FMTOS find and calculate the failure intensity, upper limit, double reliability marginal values of the 90% resource of the working state change. .A source of error that leads to a random change in the measured current value, that is, the study of the appearance of high harmonics in the measured current as a result of transient processes occurring in the energy system and short circuits as a result of the transition of magnetic materials(generators, power transformers, etc.) to the saturation part of the magnetization characteristic
