发明名称 METHOD FOR INFLUENCE CORRECTION OF DISTURBANCE FACTOR THAT CAUSED MEASURING VOLTAGE DISTURBANCES
摘要 1. A method for the correction of the factor interfering with the voltage measured with a device with the indication range regulated with a change of the reference voltage, characterized in that to the signal input of the measurement device, a correction voltage is supplied, which is proportional to the value of the interfering factor and at the same time, to the comparative input of the measurement device, auxiliary voltage is supplied, of such value that the numerical indications of the device correspond to the current value of the interfering factor, and further, to the comparative input of the device, a reference voltage is supplied, and to the signal input of the device, the measured voltage is supplied, where the reference voltage is a sum of the correction voltage and the base voltage of such value at which the indications of the device correspond to the measured value.2. A correction circuit for the impact of the interfering factor on the measured voltage, consisting of a measurement device with two inputs - a signal input and a comparative input, characterized in that the positive terminal of the signal input (2) of the measurement device (1) is connected with the switching pole of the first section (4) of the switch, whose normally shorted pole is connected with the positive pole of the measured voltage (5), and the negative terminal of the signal input (2) is connected with the switching pole of the second section (6) of the switch, whose normally shorted pole is connected with the negative pole of the measurement device (5).<IMAGE>
