Equipment for the technical condition of the grounding device

摘要

The invention relates to the field of electrical measurements and can be used to assess the state of electrical grounding devices.; An apparatus for determining the technical state of the grounding device comprising a master oscillator, current and potential electrodes, a digital recorder with blocks of a microcontroller, ADC, keyboard, display, data storage, data transfer, the matching device, sensors of the electric and magnetic field, a current meter, characterized that adds a second magnetic field sensor and a comparator, to whose inputs the two magnetic field sensors are connected, and an output connected to mikrokontr Weller registrar.; Magnetic field sensors simultaneously determines the magnitude of the magnetic field intensity above the ground at two points perpendicular to the track structures in a comparison block is determined direction of movement to the grounding connection element, together with the values ​​of tension is transmitted to the digital recorder and displayed to the operator.; The proposed device takes measurements to determine the technical condition of the grounding device automatically calculates parameters of grounding devices, transmits data to the PC, in addition, searches for the route by means of simultaneous measurement of the magnetic field intensity by two sensors, thereby reducing the number of measurements to search therefore substantially reduce the time and labor costs.
