Abstract
Automatic system for electric vertical boring. Automatic system for drilling vertical electric determining the geological court under item on applied calculating apparent resistivity, for which uses a pair of electrodes that are driven into the ground, which makes circular electric power generated in a power supply, and whose value is measured by an ammeter. At the same time measured with a millivoltmeter the tension that appears on a second pair of electrodes situated symmetrically in relation point of the first half electrodes; as is made to set aside differential mode different noises that may falsify the measure. Power supply is connected to switches to invest the current period. Differential output is connected to switches for reversing the polarity of the voltage at the negative half, this being filtered signal and measurement. Different switches are synchronized by a clock and insulated by optocouplers. (Machine-translation by Google Translate, not legally binding)
