Description
The Lightning Protection Tester LPT-1 is used to diagnose the state of grounding devices, and is intended for measurements in order to determine the impulse resistance of grounding conductors of high-voltage line supports and stand-alone lightning conductors.
The Lightning Protection Tester LPT-1 is a portable equipment that generates voltage and current pulses of aperiodic form with given amplitude-time parameters and measures the amplitude values of voltage and current pulses.
