All multi-limit current transformers can measure currents of different ranges with sufficient accuracy in the control systems of traction power supply devices. However, a common shortcoming for all of them is that when it is necessary to change the measuring range, the controlled gravity power supply device is disconnected from the power supply, ie production or technological process is forced to stop and disassembly and assembly work is required. This leads to unforeseen, forced interruptions in the operation of electric trains in the traction power supply system, including on electrified railways. When the range automatically adjusts the current transformer core goes to saturation, it automatically adjusts the current ranges, which expands its functional capabilities. Therefore, the creation of auto-adjustable current transformers in the process of measuring the range is a pressing issue today.
