Electric current measuring device, counts pulses, corrects for measuring errors, and classifies summed measuring intervals

摘要

The device has a low-resistance measuring-resistor (1) connected in the electrical cable to a device that consumes electrical power. A device (2) converts the measured values into equivalent electrical pulses. A control and processing unit (3) counts the pulses and corrects for measuring errors, sums the measuring intervals and classifies the sum in accordance with predetermined specifications. A power supply unit (6) is connected to an energy source, the pulse generating device (2) and the control and processing device. An Independent claim is also included for a method of error correction in current measuring devices.
