Voltage dividers DNE-25 (hereinafter - DNE-25) are designed for large-scale conversion of high AC voltage (single-phase AC network with nominal voltage of 25 kV, AC frequency 50 Hz) into AC voltage for supply to the inputs of low-voltage measuring devices.
The principle of operation of the DNE-25 is based on the method of capacitive division of high AC voltage. The high-voltage arm of the DNE-25 is formed by its structural elements, while the low-voltage arm consists of precision capacitors located on a printed circuit board. On the same circuit board is a voltage amplifier that provides matching of the output impedance of the DNE-25 to the load. The DNE-25 is powered from a unipolar DC source.
