КV4080 is a digital measuring, fully programmable device from the 4080 series, designed on the basis of microcontrollers. The device is used to measure middle/high voltage in electrical substations and power plants.
It measures the secondary voltage of a voltage transformer with a nominal secondary voltage of 100 VAC (or another voltage in the range of 60-220 VAC) and shows the primary voltage in kilovolts. KV4080 is powered by the measured voltage. The unit is designed to be mounted on boards in control rooms of electrical substations.
