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.
