Monitoring the state of grounding devices
MEASURING COMPLEX "GROZA-1"
The measuring complex "GROZA-1" is applicable for diagnostics of the state of grounding devices, intended for measurements in order to determine the impulse resistance of grounding conductors of overhead transmission lines and stand-alone lightning rods. The complex is a portable equipment that generates voltage and current pulses of an aperiodic shape with specified amplitude-time parameters and measures the amplitude values of voltage and current pulses. Power is supplied either from a 220V / 50 Hz network or from a built-in 12 V storage battery. The complex functionally consists of two components: a voltage and current pulse generator GINT, GINT.000.000.000, (hereinafter referred to as a generator) and a PIK voltage pulse meter -1, PIK.1.000.000.000, (hereinafter referred to as the meter). The generator is designed to create aperiodic voltage and current impulses in the test object with specified amplitude-time parameters. The meter is designed to measure the magnitudes of the amplitudes of current pulses.
MEASURING COMPLEX FOR DIAGNOSTICS OF GROUNDING DEVICES "KONTUR-1"
Measuring complex "KONTUR-1" is intended for carrying out work on diagnostics of the constructive implementation of grounding loops and measuring the values of the standardized parameters of grounding devices in accordance with the current regulatory documents. Complex "KONTUR-1" is a portable equipment and is used both for work in a complex electromagnetic environment, both in the open air and in closed rooms.
With the help of the measuring complex "KONTUR-1" it is possible to determine the standardized parameters of the grounding device, such as: charger resistance, touch voltage, step voltage, coupling resistance, contact resistance, etc. The complex "KONTUR-1" can also be used for measuring soil resistance, searching for damage to cable lines, pipelines, etc.
