Measurements and modeling of current impulses in the lightning protection system and internal electrical installation equipped with household appliances

Open air experiments were conducted of impulse current distribution in the lightning protection system, supplying cable and electrical installation of a test house equipped with electrical and electronic household appliances. Impulse currents were injected from the generator into the installation. Current distributions in elements of tested system were measured with multi-channel electro-optical system. To verify the experimental results the simulations of surge current in the test house modeled in ATP-EMTP were conducted. The obtained results show a good agreement between measured and numerically simulated currents and significant influence of frequency dependent parameters of the test house elements on both the amplitude and the shape of current waveforms.
